Problems started with the power steering leak. It has leaked all over the engine and alternator. I suspect it went out because of the leak. I have replaced the alternator and the three belts back(non serpentine) and now it's having a similar problem. While I was driving the gas seemed to no longer respond as it should. It was shutting off the engine, so it stalled. I try turning it over and it turns it just doesn't ignite it seems. We've even put gasoline straight in it and didn't spark or ignite. A few times it did turn over but as soon as you hit the gas it dies again. Man I need a clue, can you help me?

Hi,

Since you had a leak and things got wet, I have a feeling the crankshaft position sensor may have been damaged. Do me a favor. I need you to check for spark to the plugs. Here is a link that explains how it's done. Since it won't start when you prime the engine with fuel leads me to believe there is no spark. But we need to confirm that.

Now, if you haven't already, check for diagnostic trouble codes. You will need a scanner to do it. Here is a quick video explaining how it's done:

If you don't have a scanner, see if a local parts store will lend or rent one to you. If you do have one and it provides live data, I need you to check for an RPM signal when the engine is cranking. If there is no signal, my first suspect is the crankshaft position sensor.

It is located behind the timing belt cover. I attached a pic of it. Interestingly, the engine will run without a crank angle sensor signal, but will not start. Once the sensor detects TDC, the data is stored until the next re-start.

I attached a test for the sensor. See pic 2

Okay, so I got a cam and a crankshaft sensor, installed the cam, have not done the crankshaft yet. I hooked up the scanner and there's nothing. Tried 3 different scanners too, still nothing. Oh yeah, now on the inside fuse panel box everything works properly except there's one fuse that doesn't register at all and I don't know why and it is the starter or ignition fuse. I swapped it with a working one and same. I believe it's labeled as starter fuse if I remember correctly, that could be the reason, it seems pretty likely. I'm still going to replace the crankshaft position sensor and see what happens. So if its the fuse box issue. What would I want to do?

I attached two pictures below. One is the fuse box under the hood (picture 1) and the one under the dash (left lick panel). Can you tell me which fuse you are referring to? Also, I want you to remove the fuse and check if there is power available to the fuse. Here are a few links you may find helpful:

In the under hood box, there are two ignition fuses, ign 1 and ign 2. Have you checked them? Ign 2 fuse is tied directly to the starter / starter relay / ignition switch

Pic 3 shows the engine fuse under the dash. That powers several engine electrical components. Make sure it is good. Also, check the fuses under the hood indicated in pic 4. Pic 5 shows ignition 1 fuse. It shouldn't shut the engine down but other switched components.

Let me know.

Slot 3 inside fuse panel, so test the slot and see if it is receiving any power without fuse.

Hi,

Yes. With the fuse out, only one side will get power. You can check with a simple test light. If the light is dim, that is an issue as well as if it doesn't turn on.

Let me know.
