I had this problem one time. i checked spark, fuel pressure, fuel pump, coil pack etc... i gave it to my friend to work on and he said all he had to do was change the spark plugs. they didn't look bad but it worked great after he did that. not sure if it will fix your problem but its a cheap try

Maybe the gas pump or the ignition. Bring it to a near auto parts store and they will diagnose with a scanner.

No start has spark injector pulse, fuel, no codes


did you fix this yet, old post.
which engine, we cant guess that. ever.? (we know it's not a diesel)
if the engine has spark and fuel
and it dont start:
it's flooding? (spark tips soaked in raw fuel, ) we look at them......
did you try the operators guide trick, cranking with wide open throttle?
this cuts fueling , clearing a flood condition.
spec, is 120 to 150 PSI. 4.0L
or 4.7L?
good spark to ALL cylinders is the correct test, not just 1.
does the timing light show correct timing? cranking? spark timing?
ever do a tuneup, with new spark plugs yet.
If the above is true it will start. or at least on test fuel.

one way to find problems like this , if the spark is good.
is to cut all fuel injections. (i kill the fuel pump, ask how.)
and start car with test fuel, if it runs for 3 seconds each try.
then all is good , engine and spark, if not , not.
a simple test. that is. and works on all gas engines.

watch scotty.

in this case he assumes the engine is good. and timed right.

I can run any engine, with no fuel in car. sure can.
and is safe to do.
use CRC.

Verify if there is spark or not when cranking the engine over. If not, could be the pickup coil inside the distributor-this is what tells the control module what position the crankshaft is in, for delivering spark at the right time.

Ford F-150, 1996, 4.6 L 6 cyl. auto, benn cranking & running fine, all of a sudden after sitin a week, engine spins overs, but no start. When I release the start switch, sounds like it wants to crank....


If you are getting a good stream of fuel then you need to see if there is spark. Simple enough, pull one spark plug wire and insert a screw driver into it, make for sure you are only touching the plastic or rubber handle hold part of the metal on the screw drivers shaft near something metal on the car. If it is producing a white spark you are good. If not then check the alternator, it could have a short.

Then I check the plugs. If they are bad it would make it run rough, but they would have to be really bad to keep it from starting at all.

If you have fuel and fire the only problem left is timing. For this you need a timing light. Find the timing mark on the front of the crankshaft. (lower pulley) then hook up the light and clamp to number one cylinder. If it is in time, has fuel and fire then the only answer left is that you have some major problems with the top end.

1985 Ford F-150 Truck (EFI) Fuel Problems


Same problem with my 85 F-150 5.0 EFI---turned out that the fuel pump relay under the hood was teriffically corroded on the inside (I opened up the relay to look inside). When I checked the voltage at the fuel pump it would show 3.5-6 volts instead of 12 volts.

I was thinking fuel blockage or perhaps failure of the in-tank pumps. Sometimes the truck would start and run, othertimes it would neither start nor run. Typically, if running it would stay running until turned off (where the relay had to break).

Changing the green fuel pump relay fixed the problem--12 volts now at the pump and no reoccurance.

Good luck--let me know if this fixed your F-150.
