I thought that my pump was dead, but it turned out that the fuel filter was clogged. I replaced it and am getting fuel up to the rail but i think that my injectors arent firing.. I checked for spark at the coil and i have spark.. Its a 1993 5.0.. Any help is greatly appreciated.

Wondering if there is a relay or fuse for the injectors and the location of it..

If your filter was clogged to the extent of stopping fuel flow, it's likely debris have also clogged your rails and/or injectors. I would have them all blown out to make sure they're free and clear. If you have a Chilton or Haynes there should be a wiring diagram for the injector system. You can do either/or first, but I would definately have your rails and injectors serviced if there's that much debris in the lines.

Take those rails off and clean the injectors with some carb cleaner. Also check all your fuses as well.

Thanks, i havent gotten ahold of a repair manual yet.. But i will remove the rail and injectors and clean them out and see if that helps out.. I checked all fuses under the driverside dash and they were all fine...

if you want to borrow mine lemme know. and autozone carries the injector / ac line removal tools as well.

You may want to use a noid or test light to check if your injectors are not pulsing. It's somewhat common on foxes and there are a few different problems that can cause it.

Thanks spex but I picked one up when I went for food. I'm going to give it another shot Thursday morning if the weathers not eff'd. Hopefully it's clogged because me and electrical issues aren't the best of friends.

The no brain way to fix a no start. I still use this as a reference when my 5.0 starts acting up.

Fox guys will be wise to keep this one handy.

[Ugot8UP]

Awesome bro! thanks....

[beyondspexj]

time to go pick up a spare tfi for me then lol. a bad tfi would allow the car to shut off while running as if the ignition switch was turn off correct?

[Sinister]

yup!

[Ugot8UP]

Took off the rail... that thing was a B! got it off and hosed everything down and still no start... Was quoted incorrectly on a new FPR so i didnt get it ( stupid of me ) I removed the hose and could smell gas so i know thats bad.... If that doesnt fix it what next?? Oh also used the noid light and all the injectors are firing... Im guessing a new TFI?

[Sinister]

no fuel smell? outta what hose? hey, if ur fuel pump is turnin on....you should be smellin somethin! if ur tfi took a dump, you wont have no spark.

[Ugot8UP]

The vaccum line for the fpr smelled like gas. The fuel pump turns on and I have spark. But no fuel pressure, either my gauge died or the fpr isn't holding it anymore.

[Ugot8UP]

New fpr didnt help, going to drop the tank and check the feed line from the pump.. By the time im done ill have a new fuel system lol

[Ugot8UP]

Found the problem.. It was the little rubber hose that connects the fp to the line leading out of the gas tank... It was dissolved and torn... Replaced it and she fired right up!!!! Thanks for all the help..

[Chris]

Awesome news bro. Shoulda gone for braided steel fuel lines and beefed up the pump, go E-85 and top it off with a phat blower.
