SOURCE: 2000 chevy surburban 1500 will crank but no start. waited one day

replace fuel filter first then test fuel pump with a rented fuel pump tester regulator test pressure while running then pull hose on the fuel pressure regulator see if the pressure goes up if it does then it does not need replacing you will need to replace then fuel pump and fuel sock, and if you ran it lower than 1/4 tank you may have over heated the pump.

SOURCE: need to try to identify transmission from vin numer

Vin decoder available at www.ramchargercentral.com If that doesn't provide the info, then the members there can help you figure it out with nothing more than a photo or description of the truck.

If it's an 80's Dodge with an auto trans, then it is either a 727 (3 spd) or 518 (3 spd w/OD)...you'll know it's OD because there should be a button on the dash for it.

SOURCE: reverse won't work on my 1994 GMC Surburban

If you have no reverse, more than likely, you have either a stripped or broken sunshell, assuming you have the 4L60E transmission. Are you absolutely sure you have all forward gears? Another indication of the sunshell being defective, will be no engine braking in manual second.

Reverse won't work on my 1994 GMC Surburban 4x4. Only 90K miles, truck is in great shape otherwise. All other gears work fine. Tranny fluid looks and smell fine, it was changed in the last 12K miles.

Not able to reach the wires on my starter on 1996 gmc surburban


Look under the hood on the pass. side and down by the frame you will see the main power wire that runs from the batt. down to the starter.There is a wire clamp that has a 13mm bolt which secures the wire to the frame.Taking this off will allow more slack to pull the starter down further to access the wire.

Good Day,

Code P0102 indicates MAF(Mass Air Flow) sensor circuit, low frequency detected

Code P0300 indicates Random Cylider miss fire, meaning missfire in more than one cylinder

The misfire could be a result of the mas air flow sensor being faulty.

Hope this helps for now

Let me know what size motor and if it's 2wd or 4wd and I can get detailed instructions for replacing
