ok check it out guys i bought an 86 base model not running so me and a buddy checked it for compression thats good it was flooded so we fixed that changed the gas that was in the car because that was no good checked coils for resitance and changed plugs.everything is ok but i still dont get spark could it be my ecu also when i turn the key over the lights on the center dont light up just the door brake and hatch if i do need an ecu where can i find one for REALLY cheap and is there an upgraded one? plz i need help should i just sell my ****?

 

how are you checking for spark?

don't be cheap and rely on used crappy plugs, buy NEW ones!


i find that most ignition problems stem from people not simply replacing used worn out spark plugs. in these cars they take a fair amount of abuse and can sometimes appear to be ok but in fact are fouled.

 

well my mechanic brought the plugs and said they were ok he took them out of his he checked with a screw driver or something i was cranking it

well IF you need a ECU i got one!! but i would trouble shoot other possibilities first
is the crank angle sensor good?

 

other possibilities are a faulty or unplugged crank angle sensor, bad grounds or connection at battery or faulty coils but this is rare so is a faulty CAS.. so i would start by checking grounds and battery connections.

 

yeah my crank angle sensor is good like i said me and so cal rotor trouble shooted alot

 

my ecu appears to be from the junkyard you think i have a short circuit somwhere and how would i check for a short i have a multi meter

 

other good possibility would be a simple blown fuse (30amp EGI fuse under the hood), this would probably mean there is a problem in the control system though but check to be sure it isn't blown first.

 

no its fine no fuses are blown

 

OK an update, coils tested out good, as did the CAS. The plugs that were in the car were for a **** ton motor. I had a fairly new set laying around. The car looks like it has been sitting for 5 something years. We got rid of a half tank of crappy gas, as well as blew out the fuel lines. The ecu had ( N326) junkyard paint on it, and a broken harness clip. Most of the fuel lines were loose or removed. I have a ECU I am getting later today, BUT it seem that the harness might have a short. I am basing this off the fact the ecu has been swaped but still no spark. All fuses are good BTW and the battary is brand new.
