Help! start.no start??

[looney1316]

are you talking about all the shiny black gunk lerking behind the throttle body in the intake because i got that

 

[bill5674]

DUH!!! sorry forgot what i was writing and got a head of my self.i meant i swapped out the whole distributer,lots of corrosion ,and by the time you add up all the componts it cheaper to replace..car runs and idles great now......srry getting sleepy

 

[looney1316]

thanks that is clearer now, i'll type to you later

I had the same symptoms

I had what exactly sounds like the same symptoms as you. Would not start on warm days, but if I let it sit for 10-15 minutes after initially trying to start it, it would start fine and start o.k until the next day. It would start fine spraying a little starter fluid in the throttle body, which initially led me to believe a fuel delivery problem. I went thru all the trouble shooting as outllined in your previous responses, verified spark, checked resistance in each injector, fuel pressure and leak-down rate, changed fuel filter and strainer on the fuel pump, pulled fuel pump and checked for any cracks/leaks, tried new gas cap and verfied settings of the TPS (cleaned out the throttle body while I had it apart). I thought for sure it was the TPS sensing a flooded condition but I also could not eliminate the ECM as the culprit. It ended up being the ECM. I'm not saying yours is the culprit, but from what I read you have the same symptoms as I had. I suggest you go through the list above if not done already, and eliminate as many possible causes as possible and narrow it down to potentially one or two. I ended up getting my ECM through a local dealer and it was a Delco remanufactured unit. Right after that, I checked Zip products and they had remanufactured ECM's at a very, very reasonable price.

hey ronnie..sounds you had fun too .i think he said he already swapped out the ecm....

 

[bill5674]

any luck yet??

 

[looney1316]

it is at the shop getting a flywheel get it back tomorrow will let you know

 

[looney1316]

still didn't get time to test everything when i do i will let you know what i found

 

[tdr1919]

did you check to see if the ECM was putting out any trouble codes? you did'nt mention that. you could have a faulty EGR valve, if it remains open it will create a hard start or no start situation, you will have spark, fuel pressure but the intake manifold will have this vacuum leak from the EGR being open and not start

[looney1316]

i have no SES light so i assume it is not storing any codes

 

[looney1316]

can my injectors be causing this problem,here is what i got. tested cold.1-16,2-16,3-10,4-8,5-5,6-16,7-9,8-16//tested hot(will not start).1-16,2-16,3-10,4-8,5-5,6-16,7-7,8-10 i know i need new injectors but can it be causing my problem if 2 of them drop off a little more when hot.funny thing is it still run with only a little miss and no rise in temp i stay around 160.

 

[bill5674]

are we talking about the resistnce ?i think they should all be about 15 ohms.

 

[looney1316]

yes and as you can see i am all over the place

 

[looney1316]

ordered new injectors today i will let you know how it works out

 

[looney1316]

holy s**t we just put in injectors from fic what a change,it is like a new car,and so far it starts hot, to jon a fic thanks, great service,to B.XXX i would like to say thanks for helping me but i can't because i helped you.so thanks for coming over and bringing tools and letting me help you,great job

I think I read on a thread here that a shorted injector can cause the ECM to shut down a whole bank of injectors. Each bank is wired in parallel.If that is true than if you had one on each side short when hot you would have a no start.

glad to see she is up and running,hope that does the trick...bill

thanks bill
