Thanks.

A rebuilt motor should be around $50 depending on the store and where you live.

Have you replaced the fuel filter? It;s under the drivers side in the frame rail.

Inside or directly under the distribitor cap is a plastic ring with either one or two wires attached..... these devices fail and not allow the engine to start.
It happened on my 88 chevy (305 cu in.). a quick fix is to replace it with a new one.. (Advance Auto) or other parts store.

there are 2 main things that cause fast idel. the first is the computer is malfuntioning and the second is the TPC throdle posistion sensor

could be bad headlight switch

check for tune up
check for vacuum leak

distributor cap worn plugs worn

reverse synchronizer isnt getting proper lubrication or is worn down. Check lines, and change filter and screen or fluid. But normally in cases like this a gear has dropped and wont grip because the teeth cannot clamp when trans wants to spin.

Hope it works out! It can be expensive

sounds like tbi has gone out on it thats what happend to my 88 silverado
