94 suburban won't start..

I have a 1994 Chevy Suburban 5.7 liter V8 that will crank over, but not start. I've recently noticed that it has been harder to start. I can hear the fuel pump start when I turn over the ingnition key. I can smell a little bit of gas when trying to start it. I'm not sure how to test for a spark.

Please help...

Thank you in advance for reading and responding to this thread.

get one of those spark testers or another spark plug. connect one of the wires to it and set it on the engine block. get a buddy to crank it over and watch for spark. the first thing you should check assuming there's no spark is the distributor cap& rotor. if thats good check the coil and ignition module. also make sure the distibutor rotates sometimes the pin shears and the gear spins on the shaft.

Thanks, I'll give these a try..

If you are getting spark, fuel filter is a very cheap thing to replace (about $6.00). Worked for me after mine started getting harder to start and gradual loss of power.

Thanks, jimh for the advice. I had found that my coil wire was bad. I replaced the cap/rotor and coil wire that took care of my starting problem. However, where is my fuel filter located, and can I replace it myself w/o any special tools.

Thanks, again for your reply...
