Fuel Pump Relay Clicking on 94...Help!!!
 
Hey Jeep owners...94 4 cyl....try to start... fp relay clicking after I turn her over...when the clicking stops you will hear the pump activate and it will start...after that it will work properly unless its shut down for a half hour or so then the clicking again....also the clicking is considerably slower in cold weather and may not start at all?????Any advice would be a great help im a really frustrated!:banghead:

uh, replace the relay?....or check voltage to the relay....low voltage will cause that.....

relay and pump have been replaced...checked voltage...ground...regulater...filter...not sure what else besides ECM that is almost $300..ouch!

does you check engine light come on when you turn the key on (not all the way to start) or does it take it awhile for it to come on and then your jeep will start?...and you can find used computers from places like daveysjeeps.com for around a hunnert bucks...

yea...when you turn the key on just the brake light is on?? After you turn it over and wait for the relay to stop clicking the check engine light and also the seatbelt light(which start to flash at the tail end of the clicking) stay on on and it starts right up

that's a classic symptom of ECU failure...it'll only get worse.....you can replace the 3 capacitors on your ECU yourself, which is usually (99%) the problem with the ECU.....do a youtube search for ECU Brain Surgery....it's fairly simple and only costs like 10 bucks for the capacitors....all you need is some modest soldering skills......or like i said, search online for a used one....

going to give it a go on the capacitors...try to save some dough.....I appreciate the good advice...thanks
