Have a 99 dodge dakota, will not start. I have replaced the fuel pump, the carberator is good, checked all relays. Can you give me some suggestions on what else to check?

this is fuel injected it may look like a carb but its throttle body fuel injected,if you look down the throttle body while cranking you should see fuel squirting into the intake if not hold a piece of paper under the injector it should get wet with fuel.if this is happening then check for spark at the plugs,if you have no spark then you will have to check out the ignition system.if you have no fuel coming out of the injectors then you will have to check the injectors powers and grounds.if this is good then you will have to check for fuel pressure at the throttle should be about 15-18lbs.also check to see if there are any codes in the pcm that could help in diagnosing.

Will the throttle body cause my car not to start?

not usually, the throttle body is where the air and fuel mix before being distributed to the separate cylinders. (unless its direct port fuel injection, in which case the throttle body is only the engines air inlet. the part itself will not cause the car to "not start" hope this helps

Where are the fuel injectors located at on a 1991 cavalier with a 2.2 motor

Is the car fuel injected? you sure it doesn't have throttle body injection? if it is point injection you will see the silver fuel rail right on top of the engine, going into the head. If it's throttle body it will only have 1 injector on top of the carb(or throttle body).

Throttle Problem

Well 2002 will be port injected,so the throttle body only adjust air flow.Try cleaning Mass Air Flow Sensor and replacing your fuel filter.Make sure that your air filter is clean.If you havn't had a tune up in 100,000 miles then it's time.It could be the TPS ,but would try the others first.Well hope this helps,and good luck.

Vehicle stalled out while driving, will not kick over

There is no carb, either throttle body or fuel injection.If it was fuel related it would not cause all the lights to come on.Sounds like electrical and will have to be tracked down and diagnosed. Your computer may have gone out but that has to be diagnosed.
