HelloThe Engine and Automatic Transmission (not applicable to manual transmissions) in this vehicles drive train are fully electronically controlled by a computer called the PCM and TCM (Power Train Control Module, Transmission Control Module). When a problem like this or other drive-ability related problems occurs the computer stores a record of the problem (there are of course some exceptions to this, like the fuel pump, engine coolant temperature sensor and MAF sensor for instance) in the form of a fault code in its memory, to read these fault codes you must have the systems memory scanned with a special tool. Once the fault code(s) are read you then must perform the appropriate diagnostic testing to find and resolve the problem(s) DO NOT REPLACE ANY PARTS UNTIL A TRAINED TECHNICAIN HAS DIAGNOSED THE PROBLEM TO AVOID SPENDING YOUR HARD EARNED MONEY ON PARTS THAT MAY NOT CORRECT THE PROBLEM. Also always check fuel pressure for correct spec for your make and engine type.

unplug your mass air flow sensor i havd the same problem with my 97 tahoe unplug it and it should run

If you mean it is locked in Park position the first thing to do is press the brake pedal and verify you have working brake lights.

Possibly a problem with the gear computer. I suggest you have a mechanic take a look at it

Have you replaced the fixed orifice, it may be plugged with these types of pressure readings. The fixed orifice is located in the inlet to the evaporator core at the firewall passenger side.

take a look at the connector that feeds the resister that mounts next to the fan under the dash below the glove box the connectors over heat and become loose making the connection fail

Have a muffler shop put this up and look for broken exhaust hangars.

Fluid Should Be Checked Just The Same As Engine Oil. Should Be Changed At Least Once A Year For Proper Service & Reliability. Should be Driven 10 Miles A Month In 4 Hi To Keep Lubricated. I Drive A 1975 Chevy K10 PKP FullTime 4X4 NP203 & A 1980 GMC Jimmy Lock-Outs 4X4 NP205, And I Drive Them Once A Month At 55 MPH For 10 Miles (On Pavement). Keeps The System Lubed Up & Moving. Have Done This For The Last 15 Years I Have Owned Them. KEEP THEM SERVICED. Low Oil Is A Transfer Case Killer. Also Put The Correct Type Of Fluid In, Each Transfer Case Takes A Different Type Of Fluid, Call Dealer Shop For Correct Fluid Type. Some Take Dextron III Or 10-40 Engine Oil Depends On Transfer Case.
