Replaced crank sensor and still no start (cam sensor?)..

[Sinical]

...I had to order a noid light set to check the injector pulse but I've been reading and it seems the symptoms could be cam sensor as well. Is there a way to test it or do I just buy a new cam sensor and or cap and go from there?

Edit: It cranks but won't turnover. Has spark.

if it has spark, then your cam and crank sensors are working.
next step would be to check fuel. Do you have a fuel pressure gauge?

do you hear your fuel pump prime? check your fuses!

So if it has spark then both sensors are good? I was under the assumption that there could be spark with bad sensors? I don't have a fuel pressure gauge but I can get my hands on one. I checked the under dash fuses and they are OK. I have a walbro fuel pump and I hear it priming when i turn the key so I have to assume that's not the prob.

From my experience with other cars, you need a good cam and crank signal to get spark...unless TBs are different.

check all the basics for fuel. The pressure, noid lights to see if the injectors are getting a signal. Make sure the TPS voltage isn't too low, etc

OK, guess I'll just have to sit on my hands until my noid lights arrive. Thanks for the help thus far.

put the crank sensor in the right slot ????

First thing I checked Grumpy. It's in the correct slot (furthest from the connector). I made sure to set it to the thickness of a credit card also.

I swapped slots on my crank sensor after bugering up the front slot and mine runs fine. Is it not supposed to be that way?

What led up to this problem? Were you going down the road and engine shut off? Did it just not start one morning? Any repair work just prior to problem?

Just wouldn't start one day (this is back in June/July) and I'm finally getting around to it now. Replaced the starter a couple weeks before and installed a Scanmaster I did plugs, wires, etc. That's it.

When you first turn key on do you hear fuel pump run?

Yes.

One of the best places to start, when you have a no start

check the ccci fuse . It's a 10amp fuse. If it's blown, it could indicate a problem with the coil pack, ignition module or a short in the wiring that plugs into the ignition module...
