ok i have an 89 iroc l98 tpi stock heads cam i have a stealth ram 24# injectors long tube headers so my car has been sitting for a month or 2 i go to start it and it cranks but will not run. i have 42 psi fuel pressure (new pump) i installed a new ac delco ign module and a new pickup coil heres the problem good fuel i have spark but it looks week i have an injector pulse also
possibly week the niod light is verry dim when cranking and the spark lookd orange i have good compression. no start. now if i shoot fuel from my nitrous plate with the bottle turned off while cranking it will start and run like #$@%
and putter out
i have thrown parts i had in my tool box on it still with no luck
ing module
pick up coil
fuel pump

my cap rotor and wires are not that old and the injectors are not old\

also in the 2 months since i last drove it i did not have a shrader valve in the fuel rail (open to atmosphere) dont think it has antthing to do with it but fyi

last time i drove the car i had no problems i have had this car for 7 years and never had any problems with it at all now i cant make heads or tails with it
any info or suggestion would be great
thanx in advance chris imurderfords@nc.rr.com

 

What is your base timing set at? After I installed my HSR I had to (no ****) bump the timing a good 10* to get it to run decent. Also check your battery!

 

intake hase een on for long time timing is not the problem

 

I'm not a fan of noid lights, check your connectors with a DMM and see what kind of voltage you get and compare the 8. Before that, I would definately look at your battery, it may show 12V but amps/cranking amps could be low. Jumping it/ charging it would have little affect on the life of the battery.
