cranks but will not start

I think you are on the right path. We need to start with checking for fuel pressure and then move to spark.

I would just take some starter fluid and spray it in the intake and see if the engine fires. If not, then we need to remove the spark plugs and check for spark while cranking.

The other possible cause is you have stale fuel and need to fill the tank with fresh fuel. If this is the case, more then likely you need to change the plugs if you have been cranking and the fuel pump is working. If it is then you will soak the plugs and foul them.

So let's confirm this is a fuel issue and if you don't here the pump running and it fires with starter fluid then we need to replace the pump. Or you can just check the fuel pressure with the guide above.

Here is a general guide that goes through what we will be doing:

Let us know the results of this and we can go in that direction depending on the results. Thanks

thanks.. will try it ASAP.

Sounds great. Let us know how you make out. Thanks

I've used the starter fluid, and nothing. The car cranks (and I think I hear the pump) but with starter fluid sprayed into the throttle housing, it does not fire. I tried four times. In that the fuel pump requires removing the fuel tank, I'm hesitantly relieved. But why doesn't it fire? I checked fuses and relays.

Okay. One of two reasons. Either you have no compression (unlikely) or you have no spark. We need to pull a plug and hold it against the block and crank the engine to see if if fires. If not we clearly have an ignition issue.

Something to be mindful of is if the pump is working and the injectors are firing but the engine is not starting and you have been cranking it then it can foul the plugs. I would suggest if you find there is a weak spark or even what appears to be a normal spark, I would change the plugs just to make sure you are not dealing with a weak spark at this point. You may have fixed it with one of the other repairs but now have fouled plugs which is causing it to not start.
