i posted somethin earlier about this but i wanna post somethin about it again bc i found out some more stuff that might make a diff. i just had a b18c swap into a 94 teg and rarely it will not start, but as soon as i tried to crank it it will start. sometimes it starts in 2 min. or sometimes like a hr after i already tried to start it once. someone earlier on this forum said it could possibly be the fuel relay. the cap was replaced during the swap and everythin runs normally when it is runnin it never dies on me while the engine is already runnin. i took it to a shop and they said they couldnt get it to not start for them. this prob. only occurs when it is hot outside, so they let it idle for like 20 min and drove it around a bit so it could get hot but they couldnt find anythin wrong with it and i havent had the problem for about 5 days now. i feel like it is the relay but any other ideas it could be bc i doubt it is the fuel pump or filter?

 

How new are the plugs\cap\rotor?

 

cap is new but not bran new it was changed out during the swap and the rotor and plugs not sure but they should be in good shape bc the motor has low mileage and according to the guy with the shop i bought it from. i mean it runs really great and the peeps from the shop that installed it even said so and they were surprised i have this problem

 

i mean i bought the motor from a business in canada

 

See if you can hear the fuel pump pressurizing the system when you turn your key to position II. Also check to see if your fuel filter is clogged.
