Intermittent Starting

[jjfoley]

I have a '95 Ranger 6-cylinder that occasionally will not start. It cranks fine, but it almost seems like there's an airlock in the system. If I let it sit for 45 minutes of so, it usually starts right up. It runs fine once it starts. I've replaced the in-tank fuel pump and the fuel filter, but that hasn't helped. Pretty frustratin'!!

First determine if its fuel or no spark. If you have a 12v test light install the tip on the coil neg. Crank the engine if the light blinks I would take the module to advanced and get it tested. I have my own tester and I heat them up with a heat gun like a hair dryer. They normally fail when hot and work when cold.
If the light doesn't blink the pickup in the distributor is bad.
If its a fuel problem I would check the fuel pressure regulator. Pull the vacuum hose and check for leaks. You need a gauge to check it properly.
A loose fuel pump ground wire will cause this. Check right kick panel,and left front of engine comp near radiator. Computer grounds fuel pump left kick panel.

Sounds like some great advice, especially the hot distributor item. I'll check it out and let you know how it turns out.
