ok ron
Customer

If your sure you have good spark at the spark plugs have you checked to see if you have injector pulse at the injectors and proper fuel pressure (32 to 45 PSI)?
Customer: replied 15 days ago.
we just put engine in an took for test ride ran good started up a few time ,then I erased code on computer an it would not start

Okay lets start with checking injector pulse and fuel pressure if your sure you have spark.

Customer: replied 15 days ago.
check injector is clicking .sprayed starting fluid into intake nothing

If you have injector pulse as well as good spark it should start, are you sure you have good spark?

Customer: replied 15 days ago.
WILL CHECK SPARK AGAIN

Please do and while you doing this take a look at the check engine light and see if it comes on with the key on and goes out while cranking.

Customer: replied 15 days ago.
OK GOOD SPARK ,AN CHECK ENGINE LIGHT GOES OUT WHEN I CRANK IT

Okay then , you going to need to check and see if you have injector pulse and proper fuel pressure. Are you able to do this?

Customer: replied 15 days ago.
HAVE INJECTOR PLUSE .BUT I MUST BORROW MY BROTHER FEUL SYSTEM CHECK,SPRAYED STARTING FLUID INTO INTAKE GOT NO RESPONSE

It should have at least tried to start with added fuel. Are you sure you have good compression as well? As I am sure you know, you need good spark, injector pulse, proper fuel pressure and good compression for the engine to start and run. Its just a matter of which one you are lacking to get this resolved.

Customer: replied 15 days ago.
OK I WILL CHECK CONPRESSION ON OEN CYLINDER

Okay let me know the results.

Customer: replied 15 days ago.
CHECKED CONPRESSION 4 CRANKS 50 POUNDS .PLUG WAS WET ,MAYBE FLOODED WILL TRY LATER AN GET BACK TO YOU

50 PSI is not good , this engine needs at least 100 to 120 PSI to start and run.

Customer: replied 15 days ago.
WITH OTHER ENGINE .YOU COULD START IT BUT THEN IT WOULD NOT START AFTER THAT UNTILL THE NEXT DAY

Are you getting this low compression on all the cylinders?

Customer: replied 15 days ago.
REAL HARD TO GET TO OTHER SPARK PLUGS WILL DO MORE TEST ON OTHER SPARK P[LUGS AN GET BACK TO YOU LATER MUST GO CHRISTMAS SHOPPING WITH WIFE NOW

Sure thing, let me know what you find and we can work from there.

Customer: replied 15 days ago.
Ok great

Post back when your ready .

Customer: replied 14 days ago.
OK RON READY TO START AGAIN
Customer: replied 14 days ago.
THE VAN STARTED UP TODAY CONPRESSION WHILE RUNNING 90 .RUN GOOD FOR A WHILE BUT WHEN YOU SHUT IF OFF AFTER AWHILE IT SEEMS TO FLOOD OUT AN WILL NOT START

Okay so where back to determine if you are loosing spark or injector pulse or fuel pressure.

Have you scanned the system to see if there are any fault codes setting?

Customer: replied 14 days ago.
Okay code po(###) ###-####340
123
453
708

The one code Im seeing in your list that could cause a no start concern is the P0340 which is in most cases caused by either failing camshaft position sensor and or the wiring to it. Have you checked it?

Customer: replied 14 days ago.
I will check it does that could that cause all the other codes
Customer: replied 14 days ago.
Would that cause the engine to flood

No it will not cause all the other codes. Try clearing the codes and lets see which ones reset.

Customer: replied 14 days ago.
Ok will reset an drive it

Please do and let me know.

Customer: replied 14 days ago.
One code po340

Okay the is the Cam sensor code and that is likely the source of your problem.

Customer: replied 14 days ago.
GREAT I WILL PICK UP A CAM SENSOR,DOES IT HAVE MORE THEN ONE

The 5.4 has one. see the link below for replacement steps. Make sure the connection to it is okay,

Customer: replied 14 days ago.
Ok picking up sensor now sjould have on in 20 minutes

Okay

Customer: replied 14 days ago.
Ok no good drove around block 6 codes erased drive around again broke down.will get in the morning when plugs dey off
Customer: replied 14 days ago.
Dry off

See what codes are resetting. Since you just replaced the engine you may also want to go back and make sure all grounds are in place.

Customer: replied 14 days ago.
Okay will check grounds.

Please do.

Customer: replied 14 days ago.
Same 6 codes reset

I would suspect you have either a bad ground or the PCM is failing. Go back in and inspect all your connections including all grounds.

Customer: replied 14 days ago.
The other engine that was in there had the same problem
Customer: replied 14 days ago.
Check engine light came on cruise light came on black smoke came out back

Then you may be dealing with a bad computer.

Customer: replied 14 days ago.
Ok will work on a xompuer a5 junkyards

Replacing the computer will require programming.
