On a lot of ford products there is a switch that goes from the fuel pump to the inside of one of the bedsides.
what this is, is a shock switch that turns the fuel pump off if it absorbs a hit.
its a really dumb safety feature but its effective.
there is a red button on it that u have to press to make it active again.
sometimes they just trip for no reason.

I have a 1999 Oldsmobile 88 that just stopped running 4 days ago.It was running fine no engine issues and when I got up the next morning it would not start.Starter fluid just allowed it to gun up once


Sounds like a fuel issue. I would make sure you have at least 45lbs of fuel pressure at the fuel rail. If not, make sure the fuel pump runs. Chances are you will need to drop the fuel tank and change out the fuel pump.

first need to make sure you have enough fuel pressure. Hook up a tester and check against the specs. if its too low, then your probably looking at a fuel pump. By replacing the filter, you allowed more fuel to flow. Also, make sure you are getting spark and injector pulse.

98 Ford F150 w/4.6l Wont start. Hear fuel pump click. Have pressure on fuel rail. Pulled #1 plug from head and plugged back into wire. Grounded plug and cranked. No spark. Changed wires 4 and 7 four days...


have diagnostic codes checked to see if you have a cam or crank sensor fault. make sure fuel pressure is at the required pressure, just testing to see if you have fuel at the valve is not enough. replace all spark plug wires. if you replaced two then all are just as old and even when they "look good" does not qualify as "they are good". Replace coil pack. start up drive away happy

Car won't start. Cranks fine, but no fire.


And do you have spark at the plug wires when it won't start? You need to check to see if you have spark at the plug wires. You can buy a simple tester for under $10.00 at the parts store and it will show you if you are getting spark.
