Hi, this may be 2 differnt issues
is your distributor turning when engine is cranked?
And I guess you have spark at plugs
do you have power to coil?
missing ground then, need few minutes to check, have not work on those for a while.
the ground is good
ground has to pulsate in order to make coil produce voltage.
so I will say Hall sensor in distributor is gon bad.
what about the control module
it is possible, sensor is cheaper and fail more often
the local auto parts do not list that sensor
one minute please
that is the control module
i will call it ignitor
if they do not sell pick up coil ot hall sensor, then look for used distribuotr.
I have replaced everything inside the distributor bought a new control module and the motor just turns over? Its not even trying to fire.
what about engine compression?
the compresson is good
I am going to re time it in the morning
sorry my computer wend down.
check fuel injectors
you have to have power on one of the wires and pulsating ground on the other one,
ok could it be spark plugs?
if you do not have that injectors do not function
disconnect each injector and try to start, if you have shorting injector it will shut system out.
ok i will try that in the morning
ok, good night!
could it be the computer? I am not getting fire out of the coil
No, I do not think it is computer. again with distributor cap off, look if distributor rotor is turning.
distributor hall sensor is sending the crank signal to computer and ignitor module bolted on the side of distributor. that is what will make coil to fire.
I can hear the fuel pump running even with the key off but no pressure @ the rail?
fixed the fuel problem it was a wire on the relay
I am starting to think that the timming chain is bad if I turn the distributor while cranking the motor it does not slow down or speed up the cranking speed and it wont fire or back fire so I am thinking that the chain broke?
Forget that just found out that this motor has gears
I have replaced the hall sensor and the same problem no fire from the coil?
aRE YOU THERE
yes I am
I HAVE ASKED YOU IF DISTRIBUTOR IS TURNING, THIS ENGINES HAVE PROBLEM WITH CAMSHAFT GEAR. BECAUSE IT IS PLASTIC AND GRINDS THEETH OF CAM GEAR.
I MEAN TURNING WHEN YOU CRANK ENGINE
yes it is turning
HAVE YOU REMOVED DISTRIBUTOR AT ANY POINT?
yes to replace the parts in side of it
WAS IT PLACED BACK IN THE RIGHR PLACE
I think so
the engine just turns over very fast
MAY BE THIS IS THE PROBLEM
IF ENGINE TURNS FAST,THEN YOU HAVE NO COMPRESSION, HOW DID YOU READED THE COMPRESSION/
I haven't checked the compresson yet
GO BACK TO OUR CONVERSATION, AND YOU WILL SEE YOU SAID THAT COMPRESSION IS GOOD. CAN YOU CHECK AGAIN IF THAT DISTRIBUTOR IS SPINING WHEN ENGINE IS CRANCKED.
i THINK THAT CAM GEAR IS SHAVED, i HAVE DONE LOTS OF THOSE CAM GEARS.
ok I will ckeck it
and please just tell me things that are confermed, otherwise we are not going anyware!
I cannot help you like that, and I realy do want to have this truck running, I have been thinking all day about it.
The rotor turns while cranking, the compression is 140, and the fuel pressure is 58.
Ok, now you have to make sure distributor is placed in the right timing position. With engine at TDC on copmpression stroke ignition rotor has to point at wire point in distributor cap for cylinder #1
distributor is the part that makes the coil to fire.
will check with you later, have to leave now, have a good day!
Check voltages according to diagram. If all OK replace distributor.
I am at the point where the motor will fire if I spray it with eather but it will not run and the fuel pressure is still 58?
So you have spark at this moment, ignition coil is working
no not yet
I have not received anything yet
How you have got the spark? it is the same signal that is the same for computer to operate injectors.
A wire was shorting out
check this spot or harness more detailed, it is same signal
I don't see anything about the crank single?
just a minute
VREF wire is red color Signal return green
next thing to is check spout signal, yellow wire with green stripe going to computer pin 36. or you can check at distributor control if this wire gets 3V to 6V
also check voltage between pin 16 and 56 (look at previous diagram I have sended you)record voltage at time of engine cranking.
we are geting close.
I am having trouble using a voltage meter but my brother is comming over to help me tonight
ok this is where I am I ran a hot wire to the fuel injectors and it started I still need to check the timing and the firing order because it is missing and it is overheating for some reason.
Hi, at starter relay, or solenoid at engine compartment. there are few wires connected to it, those wires have fusible links incorporated in them. the one that supplies main EEC relay which inturn supplies the injectors is brown color. Fusible link N
