hi..

I need some help in troubleshooting a 383 tpi stroker...

As soon as the motor gets hot it start stalling and eventually shuts down...then I wait mayby an hour and have about 5 minutes running time before it happens again. This is a 89 Iroc that I have built with a GM Ramjet intake with 30 lbs injectors and I am running 45 psi of fuel in Edelbrok fuel rails...vortec heads with 1.6 rockers.
I have a burnt chip with the mods burnt into it but the chip was burnt with a aftermarket maf in mind but I ran out of money.

I have tried another computer with original chip and have check all my grounds at puter and relays and sensor but no luck yet....have tried another ignition module with no results also.

As soon as the motor gets hot I lose pulse signal at injectors...?????

help me please ....I am running out of time since winter is approaching fast...lol

How did you verify the injectors are not pulsing?

 

Hi Mike,

Friend of mine is a mechanic and has some kind of trouble light for injectors....but we found the problem....it is the ignition module....mine was screwed up and the one I bought was screwed up also right out of the box so I spend 1 week for nothing of troubleshooting.....that is what happens when you are an amateur I guess...

Nothing to do with being new to cars, you got the problem, but the parts house got ya. Generally you expect a new part to work.
