I use to have a stock fuel pump and i installed a walbro ever since then the walbro doesnt want to turn on we tested the walbro and its fine it seems like its not getting power or no ground and we check the fuses on engine bay and under the dash

 

..........

 

check your main relay

 

i did already i switched it with my friends car and it still was the same

 

Do you have or can you borrow a multimeter or 12V test light, trouble shooting an electrical issue is almost impossible without at least a test light, you can get a digital multimeter at Radio Shack fir $20.

There are 3 fuses that "power' the PGM-FI Main Relay.

What is the MM&Y of your car? 94

 

sry to interject stateofmind. but could the main relay be messed up if when you turn the key to the on position the lights on the dash dont light up? cuz ive been experiencing the problem of my car shutting off after driving it for a while, or starting and then shutting off immediately after a hot sit. and these symptoms seem to lead to the main relay. but when i turn the key to on sometimes the lights light up and then stay on and the check engine light goes off and the fuel pump primes for 2 seconds. if the fuel pump primes, isnt the main relay okay?
someone please help me out cuz this thing's been buggin me for a while.

 

sry i have a 99 prelude base model btw with 120000 on it

 

You should start your own tread, although problems may be similar it will get too confusing trouble shooting different issues in different cars for different people. 94
