If a 1990 Chevy Lumina APV engine quit while driving will crank but not start is it electrical or gas related?

Hey Richard==It could be either. You have to find out yourself. Pull a plug wire and see if you have spark and spray starting fluid in the throtle body to see if you need fuel. Listen at the filler cap and see if you hear the fuel pump run for 2 seconds whenyou turn the ignition on. If you don't it could be the relay which is under the hood lt the relay center. If the relay is good, the fuel pump could be bad. Check it out. GoodluckJoe

ANSWER.....I fixed my 1990 Lumina Euro. It was the CRANK SENSOR. It's in a hard to find place; got it from under the car, its in between the oil pan and the trany. At the top of the oil pan in the block on a downward angle. There are two other thinges in the block just above it to the right. (looking from under the car) JZ
