I can't get it to start

JA: What is the model/year of your Acura?
Customer: 2005 acura tl
JA: Are you fixing your TL yourself? What have you tried so far?

Hi Im David, thanks for visiting the site. when you turn the key on can you hear the fuel pump running for a few seconds?

Customer: replied 1 month ago.
Customer: replied 1 month ago.
I do hear it priming
Expert:  david craig replied 1 month ago.

ok, and you said that there is no check engine light that comes on when turning the key on?

Customer: replied 1 month ago.
no check engine light even if I disconnect a sensor it does not illuminate
Expert:  david craig replied 1 month ago.

ok, before you do anything else, remove the instrument cluster and check to see if there is a bulb there. if it is removed then the seller removed it which is illegal.

Expert:  david craig replied 1 month ago.

i will get you the procedure

Expert:  david craig replied 1 month ago.
Customer: replied 1 month ago.
Indeed there is no bulb
Customer: replied 1 month ago.
But regardless of that I have connected a scanner and I get no codes, i can do it again if needed
Expert:  david craig replied 1 month ago.

without a check engine light bulb, do you get rpms while cranking?

Customer: replied 1 month ago.
I do
Customer: replied 1 month ago.
Do I need to put the cluster back together now?
Expert:  david craig replied 1 month ago.

ok, and the security light goes out while cranking?

Expert:  david craig replied 1 month ago.

yes, but without the pcm seeing the completed circuit through the check engine light bulb, you will always have issues.

Customer: replied 1 month ago.
If by the security light you mean the green key light yes it goes away
Customer: replied 1 month ago.
Ok I'll buy another another cluster but I'll still be able to turn the car on right?
Expert:  david craig replied 1 month ago.

Customer: replied 1 month ago.

Expert:  david craig replied 1 month ago.

ok, who did you buy it from? private party or dealer?

Customer: replied 1 month ago.
Auction
Expert:  david craig replied 1 month ago.

Customer: replied 1 month ago.
if I leave it cranking for more than 10 sec it wants to start, like if it was flooded with gas but at the end no start
Expert:  david craig replied 1 month ago.

and you checked all cylinders for spark?

Customer: replied 1 month ago.
I have checked the front 3
Expert:  david craig replied 1 month ago.

Customer: replied 1 month ago.
One sec
Customer: replied 1 month ago.
I get spark on all cylinders
Expert:  david craig replied 1 month ago.

put a new bulb in the check engine light hole

Customer: replied 1 month ago.
Is that one bulb not gonna let the car start?
Customer: replied 1 month ago.
I should get the codes either way wouldn't I? If it get any codes
Expert:  david craig replied 1 month ago.

no, the bulb completes the readiness monitors

Expert:  Joshua Haynes replied 1 month ago.

Hi, my name is ***** ***** I will assist you. Please give me a moment to catch up on what has been done already...

Expert:  Joshua Haynes replied 1 month ago.

Ok, i see that you have checked for codes and there don't seem to be any...will your scanner allow you to see which I/M monitors have passed and which ones have not?

Customer: replied 1 month ago.
I dont think so
Expert:  Joshua Haynes replied 1 month ago.

Ok. I feel like delving into the missing mil bulb may take us down the incorrect track so we will move on from here...but we may revisit it later

Expert:  david craig replied 1 month ago.

I will take it from here.

Expert:  Joshua Haynes replied 1 month ago.

No problem, I didn't mean to intrude. Good luck, guys!

Expert:  david craig replied 1 month ago.

Just to let you know, without the check engine light bulb we will be beating our heads against the wall here.

Customer: replied 1 month ago.
I want to fix the bulb but I really doubt that a light bulb can keep the car from starting, I'm not doubting the expert but just have never seen anything like that and if that is true than I will have a different opinion on Honda engineering
Expert:  david craig replied 1 month ago.

very well, then the only thing left is checking compression. just to let you know, when a vehicle does have a check engine light bulb installed and the light doesnt come on when you turn the key to the run position, the computer is bad. So, if you still dont think the c.e.l. doesnt have anything to do with the vehicle starting, then ai would suggest to rethink that.

Customer: replied 1 month ago.
I will have to get a bulb from somewhere i don't have one on hand to replace it I'll get back to you
Expert:  david craig replied 1 month ago.

ok. let me know

Customer: replied 1 month ago.
I checked compression earlier and its between 135-140
Expert:  david craig replied 1 month ago.

ok, well we know thats not the problem, its looking like the computer more and more

Expert:  david craig replied 1 month ago.

hows it going?

Customer: replied 1 month ago.
Called Napa, AutoZone and oriellys and nobody has that style of led I'll be calling the dealership today since it was weekend when we started this little project
Expert:  david craig replied 1 month ago.

have you done a fuel pressure leak down test?

Customer: replied 1 month ago.
I have not
Expert:  david craig replied 1 month ago.

try that and see how long it takes the pressure to bleed off.

Expert:  david craig replied 1 month ago.

hows it going?

Customer: replied 1 month ago.
Got the led bulbs in today I'll solder it and get back to you
Expert:  david craig replied 1 month ago.

dont forget to do a leak down test

Customer: replied 1 month ago.
Ok
Expert:  david craig replied 1 month ago.

cool

Expert:  david craig replied 1 month ago.

hows it going?

Customer: replied 1 month ago.
Led bulb is in, I put back together the cluster but could not find my fuel pressure gauge for the leak down test
Customer: replied 1 month ago.
I'll borrow one today from another mechanic
Expert:  david craig replied 1 month ago.

ok good just let me know thanks

Customer: replied 1 month ago.
Ok I did the fuel leak down test and after sitting for 20 min it went from 50psi to 40psi
Expert:  david craig replied 1 month ago.

ok, thats not too bad.

Customer: replied 1 month ago.
what do we do now?
Expert:  david craig replied 1 month ago.

standby

Expert:  david craig replied 1 month ago.

ok, now with the check engine light finally working, have it scanned or codes.

Expert:  david craig replied 1 month ago.

if still no codes, replace the ecm

Customer: replied 1 month ago.
Is the other ecm going to require any special programming?
Expert:  david craig replied 1 month ago.

yes. you can buy one pre programmed ff of ebay

Customer: replied 1 month ago.
Is there any way I can check the ecm for being bad I don't want to start just throwing money at parts without being sure they are defective
Customer: replied 1 month ago.
Cause let's remember that I do have spark and I do have fuel, compression and the immobilizer seems fine all those things have to come from the ecm and they are there
Expert:  david craig replied 1 month ago.

there is no way to test the ecm, you have fuel and injector pulse. you have spark. you have good compression. the theft light goes out while cranking, you have rpms while cranking. check these fuses. that's the last thing.

Expert:  david craig replied 1 month ago.

hows it going?

Customer: replied 1 month ago.
Fuses are good still no start
Expert:  david craig replied 1 month ago.

replace the computer.

Customer: replied 1 month ago.
I just heard something and I don't know if it's possible but maybe you can help, the car was bought at an auction with the car being a reposession and mechanical problems well is there any way that the dealer has some sort of immobilizer hook up to the car I hear they exist and maybe that's the reason why the car won't start?
Expert:  david craig replied 1 month ago.

itss very possible there is a gps hooked up to the vehicle and the shutoff is enabled.

Expert:  david craig replied 1 month ago.

hows it going?

Customer: replied 1 month ago.
Well I can't find no gps shutoff on the car I've looked at all the wiring under the steering wheel which is where I would assume it should be and nothing, the green key light at the dash flashes 5 times when I remove the key I don't know if that means anything
Expert:  david craig replied 1 month ago.

recheck for fault codes.

Customer: replied 1 month ago.
Ok
Expert:  david craig replied 1 month ago.

let me know

Expert:  david craig replied 1 month ago.

anything?

Customer: replied 1 month ago.
Sorry I didn't get back to you sooner, the ecm is on its way same part number so let's wait and see when it gets here
Expert:  david craig replied 1 month ago.

ok thanks
