Getting the Wheeling Fever
My 1991 isuzu trooper 2.8 V6 4x4 automatic will crank and it is getting gas but wont start. What would be the best things to check out first? Any help will be appreciated. Thanx.

Roll Me Over
The old truth is that you need three things for ignition - spark, fuel, and air (all at the correct time, of course).

If this was a running engine, and now has this problem, I would start with the primary wiring - distributor, coil, coil wire, plug wires and plugs.

If the engine has been out and you are now trying to start it, you are going to have to tell us more about what you have done.
