SOURCE: 2000 Chevy Blazer Cranks but wont start...

What about the fuel filter????? Have you changed it out??? If you can spary something like a started fluid, that means it is a fuel problem. My last check, it has to be above 50-psi on the fuel pressure to make it run right. I had 35psi, but whould not get over 30mph or down hill maybe 45mph. Check both filter & pressure, but check pressure with a New fule filter!!!!

SOURCE: Will not read codes from the OBD connector

Yes the OBD Connector is fused. The fuse is a 15 AMP mini and located in the Fuse block on the Left hand end of the Instrument Panel requiring the Drivers Door to be opened for access. The fuse is located near the bottom of the Fuse Panel. It probably also feeds the Cigar Lighter circuit.

Testimonial: "It was the cigar lighter fuse.Strange that it ties in with the OBD, but it fixed the problem. Thank you for the advice."

98 chevy 12 pu cranks and has spark will not start


Question number one is the timing correct ? Did the timing belt/chain jump?
Question number two Is it getting Fuel? a plugged fuel line/filter or injector(s) can cause this, Typically anything else will throw a code that can be read, with an OBD reader that plugs in to the oblong jack under the driver side of the dash.

have you had the fuel pressure read from the pump ? i'd have the OBD codes read as will tell you which sensor/switch is at fault , that was bad luck if the pump did fail , i think it's more likely a sensor/switch issue , keep me posted if you wish

I am getting both PO715 and PO751 error codes on my 2000 grand caravan. Does this mean the tranmission needs to be rebuilt?


P0751 Shift Solenoid A Performance or Stuck Off (generic OBD description)
P0715 Input/Turbine Speed Sensor Circuit Malfunction

The service manual does not list P0751 as a valid code for your vehicle. You may want to re-check it to make sure you are reading it correctly. Also note that many generic OBD code readers cannot give complete renderings of "manufacturer-specific" codes. You may be getting this code if you are using a generic OBD code reader because there is a manufacturer-specific code present and P0751 is the closest "generic" rendering of the code that the code reader could find.

P0715 is a CIRCUIT malfunction. NO, this does not mean that your transmission needs to be overhauled. This means that either the turbine speed sensor has an electrical failure in itself or the circuits between the turbine speed sensor and the computer are defective. Electrical diagnosis needs to be done.

Please note that BOTH of these codes can be cause by low battery voltage and attempts to diagnose the circuits involved should only be done AFTER verifying that the battery and charging system is working properly.

I have a 2000 eclipse and the night before it ran fine. The next morning I went to start it and it cranks but that's about it. I checked for spark and after I cleaned the oil off there was spark, but...


Providing a accurate diagnosis is difficult. All previous advice could be correct.

I'd look into the fuel delivery issue first. The MPI (fuel pump) relay is controlled by the engine computer (ECU). If this is OK, your Check Engine Light should be off. A test with an OBD-2 code reader will tell if the ECU really is OK, and show any error codes.

If the ECU is OK, and the fuel pump is getting power, open the gas tank cap and see if this helps the car to start. (might be worn pump issues).

If you are actually getting fuel and spark, a no-start condition will generally throw an ECU error code, see above. There may be a crank or cam sensor that has failed.

The next thing to check is that the timing belt has not slipped a few teeth. This does happen. Your engine is probably a 4G64, and you MAY get away with it without bending valves. Or maybe not.

1998 dodge caravan. dash lights don't come on and it won't start. put van on computer and it read no codes.


You may have lost a major ground. The places to look are as follows; 1. Check the main battery to engine ground(black). 2. Check the ground wire pigtail that splits off from the main groun to the engine. This wire will connect to the inner fenderwell on the passenger side. 3.Ckeck for a braided flat wire without coating running from the firewall to the engine intake manifold, usually the bolt that mounts thios wire to the engine is one of the intake mounting bolts. Good luck, Dana

Missing and cutting out


A fault code reader would be a huge help in diagnosing general problems. It plugs in under left side dash and gives specific failure codes (this is what mechanics use).
You can buy an OBD-I code reader (for cars before 96) online for $79.95 or a OBD-II which reads all cars from 1996 on. It will also reset faults or engine trouble lights.

You may want to check your fuel pressure with a gauge.

or do a simple Fuel pump test:
  1. remove the gas cap.
  2. have one person listen in the gas tank at the gas cap opening.
  3. the other person turns the ignition switch to the ON position ONLY (so the dash lights come on.) Do NOT crank or start up the engine.
  4. As soon as the ignition key is turned to the ON position, The person at the gas tank should hear the fuel pump run for TWO SECONDS and then it should STOP.
If it does NOT run for the 2 seconds every time, the fault is either the fuel pump or fuel pump relay
