1988-95: Use a scan tool, or 1. Short terminals of Check Engine connector or service connector (depending on model) with suitable jumper wire. Make the jumper connection between terminals E1 and TE1. Some Check Engine diagnostic connectors are round and are located under the instrument panel. Others are rectangular and are usually located in the engine compartment. 2. Turn the ignitiion ON. Trouble codes will be indicated by flashes of the Check Engine light. Count the flashes to determine the code. If more than one code is present, codes will be separated by a long pause. Codes will continue to repeat as long as the jumper connection remains in the diagnostic connector. NOTE: If the light flashes on and off 4 times a second, there are no codes. DRIVING TEST MODE When a fault is first detected, a code is temporarily stored in the computer's memory. If the same problem is detected again during a second trip, the Check Engine light will come on. In order for this mode to store codes, the ignition switch must be turned OFF between the first and the second test. 1. Make sure the battery voltage is at least 11 volts, the throttle is fully closed, the transmission is in neutral and all accessories are off. 2. Use a jumper wire to connect terminals E1 and TE2 on the diagnostic connector, then turn the ignition ON. The Check Engine lamp should illuminate. NOTE: Test mode may not be entered if terminals TE2 and El are shorted after ignition switch is turned ON 3. Start engine and drive vehicle at 10 mph or higher. If vehicle is not driven vehicle speed signal code 42 and 43 may be set. 4. Simulate driving conditions that originally set code (if possible). 5. Turn vehicle off, remove jumper wire. The rejump terminals E1 and TE1 to read any codes that were set during the test drive. HOW TO CLEAR CODES Disconnect the computer fuse for 10 seconds, or use a scan tool to clear codes.

Well I fixed one problem, I changed out the fuel filter in a vague hope of getting it to start and it actually worked, starts fine when its warm takes like 5 seconds when its 51 degrees out, but as I was driving it home the back end started to shake and before I could do anyything I heard a break. My tire still attached to the axle shaft decided to take its own journey down the road, waylaying a mailbox and a fence. Ill have a picture up soon maybe you guys can help me figure out what I need besides the obvious wheel bearing

Jumped out the E1 and TE1 terminal and never received the fault code. Must have cleared it with bad connection. Since then I have soldered the wire ends to produce a round end that fits better.
I can't drive the Truck because it cuts off when warm. While idling it runs ruff. When I changed out my fuel filter the fuel that drained out of it was so dirty. I dumped the fuel from my tank and found some water. Flushed the tank and filled with fresh fuel.
When the rain ends I will start the truck and run until it shuts down and then check the spark by pulling a wire and attaching a spare spark plug. If fire is present I will try some fuel in the intake and see if it will start.
I don't have the money to purchase a fuel pressure gauge and hope to find one I can borrow soon.

Along with those two steps, check engine compression while all plugs are out!

My truck will turn over but will not start. I checked all fuses, relays, spark plugs, and all that is good. I can roll start the truck and it fires right and I can drive it and it runs fine. It will not start with the key any ideas? I am stuck

First test. Put it in neutral, do not touch the clutch and see if it starts. If it does test the clutch start cancel switch.

Find the ignition switch harness. Look for the black wire with a yellow trace. Connect a test light to it. Turn the key on. You should have power. Now turn the key to start, the light should stay on. As you turn the key. If it does not the ignition switch is bad. If it does jumper the black/yellow wire to the black with red trace at pin two on the cancel switch. If it starts now while holding the clutch down, the cancel switch is bad.

Well you can double check the starter relay, If you jump from the White wire Pin 5 to the Black/White wire Pin 3 that runs to the starter does the engine crank? If yes, apply 12 volts to Black wire Pin 1 on the start relay and see if the engine turns over when you step on the clutch.
If both of those work the wire to the switch or the start contacts in the ignition switch have failed.
I added a wiring diagram below.

We've replaced the fule pump, sending unit, and fuel filter.

We know that when we crank the engine fuel pumps.

However, when we have the ignition in the on position no fuel is pumped. I don't know if that is normal.

Also the check engine light does not come on. I don't know where to go from here. Can you help?
