1990 oldsmobile wont start


Chances are its an ignition problem if nothing happened by using starting fluid. Have you pulled the plug wires and checked for spark ?

1990 cutlass ciera w/3300 v6, won't start, fuel presure is 45psi, has good spark, has new crank sensor. still won't start, what next.


If it has spark, the crank sensor is working. If the fuel pressure is 45psi, that's good.

Are the injectors pulsing controlled by the computer?

Spark on only 2 of the 4 cylinders


On dis ignition systems if you have an open circuit plug wire you will lose spark on both cylinders of the coil. So however you are checking for spark,(screwdrivers or spark testers) Check cylinders 1 and 4 at the same time. A good way to eliminate the possibility of a bad plug wire is to take both wires off the coil and start the engine. Spark should jump from the coil tower to the coil mounting bolts. If it doesn't replace the ignition module.

Crossed wired spark plugs


andersonltam: OOPS! Don'tfeel bad it's a common problem. First we have to get you oriented in front of the vehicle and give you some reference points so that we are talking apples and apples OK?
Standing directly in front of you vehicle, hood up and looking at the motor, the engine sits "Transversely" (SIDE WAYS") HMM they keep doing that!
Starting with the cylinders on the front side of the motor closest to the radiator, they are
numbered as followed. To your left is #2 cylinder, the center is # 4 and the right is # 6
So the layout is even on one side and odd on the other.
On the back side you have the same configuration: # 1 cylinder is to your left, # 3 is in the center and # 5 is on the right.
back of car
(1) (3) (5)
2
to #1 cyl > 1 3 <(Dist cap)
6 4
5
( 2) (4) (6)
Front of Car

This illustration was a close as I could get using what I had, but I think you have a 99.9%
chance of figuring it out...... If you don't I'll be watching... Let me know how I did......

NO SPARK AT PLUGS


Its probably the electrical part under the ignition coils follow your spark plug wires to the back of your firewall and remove both ignition coils and there is an small electrical plate that needs to be replaced and you should get your vehicle running because I had the same problem
