Pull out the fuse panel for access to the blade type fuses Posted on Oct 18, 2009 old post and is key question on old jeeps no engine stated. Does anyone know where I can find one? Mechanic can't find used wire harness for 1994 dodge dakota. If it is not, the wire is open. Has anyone had any luck with anything else? So you have to refer to the factory legends to learn the identification symbols and then refer back to circuit diagrams to find the splice and ground locations. Do not attach the other end of the jumper wire to the relay at this time. In the event of a ruptured fuel line, raw fuel on the ground would be a fire hazard, but the engine can't run without fuel pressure.
After a cool down period the truck will normally start with no problem. The odd, erratic behavior went away. This is the next topic. If that were the case it wouldn't run with some gas down the t-body. The most likely cause is a defective crankshaft position sensor in the distributor. I found the three wires mentioned above and clean them up.
Once the computer was unplugged, the fuel trim values were lost. Relays are not responding when key is turned on. Third - remove the relay and look at the base terminals. If it fires, you know it's not getting fuel, but when it does fire , it may prime the pump enough to run. If it does not, we have to look at the camshaft position sensor and crankshaft position sensor circuits.

Lesson is, what looks like a computer issue could be water inside the car near the wiring harness that runs along the floor near the fuse panel near the driver's side feet area. The test light should light up for just one second when you turn on the ignition switch, then it will go back off. But after a while the freakiness starts again.

I have checked the fuses for it. You need to find the cause of this missing voltage. The Engine Computer turns that relay on for just one second after turning on the ignition switch, then again during engine rotation, cranking or running. You'll need to by a manual like a Haynes in order to get a decent wiring diagram.

You don't have to spend any more time diagnosing the fuel system or replacing any of those parts. There are dozens of such sensor readings and operating criteria that the computer tries to reconcile to verify proper sensor operation and engine performance. More problems are solved with new computers in their cars and trucks than any other brand of car. I have lost all electrical power to my 07 Dodge. Take off the air filter and have someone squirt fuel down the throttle body while you crank the engine. If that were the case it wouldn't run with some gas down the t-body.
The relay itself could be bad but that's not very common. If voltage is present 12 Volts , then you have confirmed that the fuel pump fuse and fuel pump relay are working perfectly. Initially had some strange issues. I Have A 1993 Dodge Caravan With A Fuel Pump Problem Image info : Resolution:1024x667 Size:144kB 13.

It´s possible bad contact Sorry my english is bad. As you drive, the computer watches the readings from the oxygen sensor s and modifies fuel metering accordingly. With no pulses from it, the computer doesn't know the engine is turning, and wouldn't know when to fire the coil or an injector. Also went and had the coil tested and that is good also. It's in the under hood fuse box! What goes wrong with Jeep starting system? I got a truck that the engine isnt firing.
Computer shows vehicle not responding. Like I said, it's a long shot. More importantly, this is Chrysler's very effective and reliable way to prevent fires in a crash. It sounds like an ignition switch or an aftermarket alarm system. You can check out wiring diagrams at! That's where a good diagram comes into play.
