My truck won't start
Hi there....
Just curious if anyone knows what may be wrong with my truck!
It is a 1999 Ford Ranger 4x4 - 6 cylinder - 4 liter - Manual Transmission
Other than it hesitating going up hills occasionally (which I think is from old plug wires) it has been starting and running fine. Now the engine won't even attempt to start. The starter works and turns over, I pulled the gas line out and it spits gas when I try and start it. So the fuel pump should be alright. When I pull a plug wire and stick a plug on the end I got no spark while trying to start nor could I get one out of the coil pack. I think that it is the coil pack that is failing, but hate to spend the 100 bucks without a second opinion. A mechanic cousin of mine believes that if it was the crank sensor that was failing that the gas pump would not pump fuel.... Any thoughts? Thanks!

Seems like the pump would still work with a bad crank sensor, but the injectors just wouldn't pulse. If you have injector pulse I would guess a bad ignition coil or module.
And the "ignition module" might be an internal part of the ECU, at least that's what I think I read somewhere...

With a test light - you can buy or borrow from a friend the correct single noid test light, or you can probably rent or buy a test set similar to this:
The entire sets usually go for about $20 if you buy it.
Just watch the light while cranking and you should see a steady pulse if it's working okay.
