I have been bashing my head against the wall long enough.

I have no fuel pulse sometimes and no spark the other. I have never had both at the same time since i put in my new setup. I have gone through 3 optis, 2 ICM and 2 Coils all brand new and those are not the issues. I have also gone through 2 different computers same result.

Before i rip out everything and burn the wiring in my car and go carb'd. Is there anything else and anyone on here can suggest.

I have a new TH400 swap to it too. I feel there is something to do with wiring to that but i have no idea at this point. I have tried Speed Inc not much help there and same result with FLP. Its before very frustrating and about ready to throw in the towel.

 

it could be bad spark plugs

also i had a problem when my car wouldnt start at all and it ended up being that the intake wasnt in all the way. lol

 

Vats system?

 

plugs are new ngk

no vats on the car

 

You have to wire the park / neutral safety switch into the wire that goes to the lower clutch position sensor. For 4L60E conversions you will have to tap into the existing park/neutral wire.

i didnt do this, would this create my problem ?

 

If vats is gone and your using a th400 you dont need to use the p/n switch at all. DId you eliminate the keyed vats as well and use a resistor?

 

am i suppose to ???
and how would i do that ?

 

Ignition switch going out

 

what year is the car?

 

would tha cause my issue ?

and the car is a 94.

 

I had a similar no spark issue and it was my Optispark connector.

 

also I hate to say check all plug wire connections possible melted wires? grounding arc?

 

Yes, and its easy to replace. 1st look at it and see if it has burn marks like its arcing. The piece is white so easy to see burn marks
