this may sound stupid, but maybe the battery is low

Hahaha yeah what he said. Or if that does not work, a new starter should do it. But like he said, check the batt first, if thats the problem, hit yourself in the head a couple of times with a 2x4 for us jk

lol at the use of caps, anyways I had this problem less than a month ago, fuel pump was shot replaced it and its been (nearly) fine ever since. Occasionally refuses to start on the first try, but almost always on the 2nd. I figure I need to replace plugs and wires and all that fun stuff if i want it to start on the 1st try every time.

if it's cranking, it's not the battery. You may not be getting enough spark, since you said two cylinders aren't showing strength in their spark. If you are getting spark, check your timing belt.

Tbelt missing 1 tooth. Replace TBelt, if not, check fuel filter, that usually helps.

95's have a known problem with their ECUs. The telltale sign it's going bad is if it spontaneously shuts down, and after a few minutes or hours starts back up again like nothings wrong.

Swap it out with a known good one.

Mine only has the problem were when its been off for awhile it takes 3 cranks to start the thing. When the cars been on for awhile it turns on the first time. ECU related, but try replacing your fuel filter, I havent so that might be the problem. Nothing big to worry about really, just hope that the car dosent turn off in the middle of a train track when the train is underway and the car dosent turn on, then you would be in a world of s... yeah you get my point lol.

The reason your car doesn't immediately fire on the first try when it's cold has nothing to do with the ECU, and it's not a problem. It's because the fuel has partially drained back to the tank after a day or two of sitting. Try priming the fuel pump a couple times when the car's been sitting. It'll fire immediately.

Now, onto the original poster's question. You have to have three things to make the engine run. Spark, fuel and compression.

You said you're getting spark although two cylinders are weak. I believe you said 1+4 are weak. This is a possibility with the wasted spark design as 1 and 4 are "partner" cylinders. The computer fires these as a pair, then fires 3+2 as a pair. I'm suspicious of this. The spark could be getting snuffed out on two cylinders, and it won't run on two cylinders. (Trust me) Check the connection to your coil pack You'll notice there are three wires. One is a ground and the other two are for the two banks of plugs. Is a wire in rough shape, disconnected? Also check around the EGR tube (underneath the throttle body, goes into the back of the intake manifold), since it gets very hot and could have melted some wires, a known problem. Check very carefully. Also, if you're getting spark it should rule out the ASD relay and cam/crank sensors.

Fuel? The easiest way to check this would be to crank it and then pull the spark plugs. Smell them. Gas? Good. No gas? Good-since you found your problem. No gas = fuel pump relay, fuel pump, fuel pump sock, fuel filter, fuel pressure regulator or kinked/blocked fuel line.

Timing--Have you pulled the inspection cover from the timing belt to make sure it's turning? Timing is the most difficult to check, since it involves more than just pulling spark plugs. Go here if you have both fuel and spark.

It could be a lot of things. If you have fuel and spark, you could also check compression since that's easy. I know it's not on a warm motor (which it's supposed to be done), but you could check for dead cylinders even if it's cold.

We need some more info to help focus on a particular part, hope this helps solve your problem.

No no, the fuel pump is probably fine. PRIME it, which means when you get in the car after it's been sitting for a while (at least a day) turn the key to the position where everything lights up (run position) but don't start it. You should hear a whining sound from the back. That the fuel pump priming the system. Try that a couple times.

Then kick it on. It might take a turn over or two, but remember, the cylinders are cold as well, so just let it take it's time.

Were you talking about 3 times the motor turned over, or three seperate cranking "sessions".

3 cranking sessions. My motor does not shut off like his, once mine is up and running it stays like that.

I'll try that too, since occasionally after its been sitting for a bit it does take a few crank sessions to get it to start. Is there any more permanent solution to this?

I had a friend run accorss this problem. He replaced the fuel pump, filter and injectors and he never ran accorss that problem again. But yeah the best would be ur filter first, then the pump, then injectors. BTW priming it 2 times worked for me so yah

i did the compression test 3 times and the way the instruction said to do it and it read the same everytime i just find it odd the every cyclander is that low also will a 98 gs ecu fit in my 95 ?

So you have fuel, and you have spark (albeit weak)

The results of the compression test are low. I know it's on a cold motor, but still, they're low.

I don't want to say you did it wrong....but....how did you do it?

If they're all universally low, I'd start looking at the timing.

Nope.
However, you could match up all the wires from the 95 ECU to work with the 98 pinouts. Too much trouble if you ask me.
