I would check the computer fuse and relay. I would also have the control module tested, usually Auto Zone can test them. I would check and make sure you are getting gas at test port on the fuel rail.

I have a 95 Chevy 1500 truck 4by 4 and I can't get it to start I tried everything it seems like it wants to start but nothing what could it be


well if it won't start it won't start...because your engine has lost 1 of 3 things that make it run: gas, spark, and compression. Don't tie yourself into knots over what it could be. Do the basics first. 1.Check that the engine is getting gas into the cylinders.
2.Check that the spark plugs in the cylinders are getting ignition current to make blue snapping sparks when tested.
3.If you have both spark and gas to all cylinders, you should do a compression test of the cylinders to know there is enough compression in the cylinders to make it run. Without good compression readings from all cylinders, no amount of money thrown at it will make the engine run better, you have to do mechanical repairs to the engine that restores compression first.

Most times, sudden no starts are gas or spark related. Check those first. Happy Holidays.

Multi-Port Fuel Injection

Amigo,Trooper II , Rodeo & Pickup
On Rodeo, Amigo, and Pickup (except 1993-95 models W/3.2L engine), connect the single wire diagnostic leads located behind the left hand kick panel together. On 1993-95 Rodeo models W/3.2 engine, the data link is located under the left hand side of the instrument panel. On all models, turn the ignition switch to the On position. At this point, the "Check Engine" light should flash. codes

Engine turned off suddenly and wouldnot start


Several things coud cause this .. none good...
1. Bad gasoline (water in gas)
2. Head gasket blown.

You can check the "wiring" (spark):
Need another person to help
1. Set parking/emergency brake.
2. unplug one cable from a spark plug and place it on the motor or other metal
3. while "cranking" the engine, look for spark at end of sparkplug wire. It will probably spark... not an electrical problem
4. Don't touch the wire while the ignition is on .. it will shock you!

Use a can of "complete fuel system cleaner" not just an injector or throttle body cleaner. AutoZone ($9).

Hope this helps!

Connecting code scanner to 2007 chry 300 & 95 dodge 1/2 ton ram


Most obd2 connection ports are under the driver side dash and can be visible without removing any panels. On some chrysler Daimler vehicles you do have to remove a panel to access this service port. If its not located under the dash then it will be located under the hood on the driver side and be capped off and labeled obd2 scan tool service. Simply plug your wire in with the key on and the engine not running and read the codes from your vehicles on board computer/ecm/bcm. Hope this helps. Good luck.

Trying to read check engine light on my 95 sunfire it has a obd2 plug but the obd2 tester wont read my codes how can i test this with out going to dealer?


Most consumer available scanners read OBDII on 96 or newer vehicles. If your car does in fact have a OBDII plug then all you need is the software in your scanner to be able to read OBDI codes...a 95 is running OBDI. Advance Auto or Autozone might have a OBDI compliant scanner for free...just tell them you have the OBDII port so they don't take up all your time digging for the adapter!

1996 merc grand marq...check engine light stays on ....and the car accelerates wothout foot on the gas peddle???


nine times out of ten your check engine light means you need a new gas cap. as for your accellerater that could be a linkage issue , if you have a broken motor mount the engine will lean against the linkage . the harder it leans the faster it goes ... the faster it goes the harder it leans
