2 weeks ago, I drove my truck home from a 2 hour long drive no problems. The next day I go outside and try to start it nothing just cranking without firing. Here's all the checks I've done on it.

1. Getting spark (nice and blue). TFI module & coil checks out.
2. Verified TDC on no 1 cyclinder & rotor location. Timing belt is still there.
3. Checked fuel pump, both relays, intertia switch, fuel pressure at the rail when the key is on (inital 40psi). Replaced the fuel filter.
4. Full tank of gas, drove an hour after the fill up.
5. Cleaned the battery terminals & verified they were tight.

Here's some other info...
1. When I changed the fuel filter and drained the rail, I got back in and cranked it. It fired momentarily and went back to the same old same old.
2. Here's another issue, when I crank it I get an odor of gas.

I thought it was the EEC (brains). So after cranking it for awhile I disconnected the computer and for ****s and giggles tried to start it. It fired and ran really rough until the gas was gone from the intake manifold. Then it would not start back up. Hooked up the computer, it just went back to cranking with no hint of firing. Then I unhooked the computer and it fired up and ran really rough until it burned all the fuel out of the intake.

I purchased a remanufactured computer and installed it. It is not that because all it does is crank without any hope of firing. Can someone help me out with this. I know it is somewhere in the fuel system or a sensor but I am lost right now.

Thanks,
Chris

 

i actually had the same problem on my 92 ranger check out my truck wont start thread ....my truck still wont start.

 

try pulling the vacuum line off the fuel pressure regulator and see if there is gas coming out of the FPR. Also check the wiring for the injectors, it seems like you are not getting fuel. When you turn the key do you hear the pump run for a few seconds then stop?

 

Pull the valve cover and check the timing of the distributor again.You know the timing belt is not broken , but it could well have jumped a bunch of teeth.When you checked TDC and rotor location , How do you know which stroke it was on ? I have seen timing chains jump 180 degrees and swore up and down the timing was OK until I checked the #1 valve position.

 

I am having the exact same problem on my '85 read something about the map and tps telling the computer not to fire i'll test and post results

 

tested tps reading between 9 and 10 volts on the sweep i think its supposed to be between .96 and 5.00 so i am assuming this is bad does anyone know how to test a map sensor?

 

I have a 1985 Ranger Fuel injected 2.3L engine with the EXACT same problem. Checked Timing Gas air and Spark. All there. Was just starting the truck. Ran great for 30 seconds then died nothing since. ANY help would be appreaciated!

 

An electric fuel pump can go bad but run intermittently. Happened to my parents Hyundai. It would work for a while then just cut off. I thought it was the TPS since the vehicle only had 38k on it. You can try thumping on the gas tank with a rubber mallet while attempting to start or rock vehicle.
