Hey

I recently bought a 87 GTA L98. A week later, the ****ty accell wires burnt up on the headers - and they had heat sleeving over them.
They are edelbrock headers, which the air tubes are in the way of routing the wires. The Car has no air system, so I cut the tubes off the headers and welded them.

I also replaced Cap, Rotor, and the wires with MSD Super conductors.

The major misfire is gone. There is a slight misfire and 50rpm - 100rpm surge.The car vibrates when you bring the idle up to say - 2000rpm.

I can not feel the misfire under load.

Also, the car takes about 3 seconds to start, which I beleive is related to this issue.

I was testing the spark from the coil pack and it was good. After I pluged the coil wire back in, I noticed the car started up right away. Switched it off, then tried to start it and it took the usual 3 seconds.

Tried it again, looks like getting fuel into the cylinders makes it start up instantly.
Ideas?
FPR?
Injectors?
Pump?
I replaced the fuel filter a few days ago.

 

What is the standing fuel pressure?

 

I'm going to go buy a gauge tonight.

 

im intrested in the cause of that because im having the same exact problems with my car on my knewly built motor...did u find out what was causing that?

i was thinking of geting the msd ingniton to see if that would fix it

 

thats nothing. my 89 Formula takes 3 times to start! The first it just cranks, the second it crankes and surges and stalls, and if I am lucky, the 3rd try it will start but not without the help of me pumping the gas!
but it runs great after that, so whatever. It has a 150K miles on it.
