Gotta Problem.... No Start....Need some help/ideas...

I've got a 98 zx2. MTX. 112,000 miles on it. No mods to the engine or anything. Last month, my thermostat went out on me, and that's the only problem I've had with it... until recently. It would take awhile to start up. It would turn over and keep turning over, but it would just take 10-15 seconds to actually fire up, and this just started within the last week or so. And then this morning.... NO START. It has new plugs, new air filter, oil and filter changed 200 miles ago. Don't have any specialty tools to do any compression tests or anything like that. Just your everyday at home mechanic. No codes popping up. Possibilities: Starter? Fuel filter? Fuel pump? Ignition coil? Crankshaft position sensor? I really have no idea where to start. I've seen so many threads regarding no start situations, but I just don't know where to start.
Please, if anyones got any info, please let me know.
Thanks,
Adam

The first thing I would do is check fuel pressure!

Welcome to AF! First things first. Is the battery fully charged and connections clean and tight?

Airjer is onto it. I would start by checking to see if it is a fuel problem. Spray some starting fluid into the intake. If it starts it's a fuel problem. Start by checking for pressure at the fuel rail. If it has pressure the fault is in the fuel injectors. Check the fuse under the hood marked fuel injection. It is a 30 amp fuse. If it doesn't have a burnt out fuel injection fuse listen for the fuel pump to run (Whirring sound) when the ignition is turned on. If you can hear the fuel pump running, but you don't have any pressure at the rail, the fuel filter is clogged up. Replace. If you can't hear the fuel pump running check the 30 amp fuel pump fuse under the hood. If the fuse is good the fuel pump relay or the pump itself is faulty. The fuel pump relay is in the CCRM (constant control relay module). It is the relay containing the fuel pump relay, the cooling fan relays and the PCM (power control module) relay. It is expensive. $200. Hope it's not this.

If it won't start with starting fluid the spark is at fault. Disconnect a plug wire and ground it to the engine as it is being turned over. If you don't have spark the most likely culprit is the 30 amp engine fuse in the passenger compartment. It supplies power to the PCM. If it checks out clean the two wire leads to the Crankshaft position sender with alcohol. It sends a weak signal to the computer to time the spark. Last of all it could be the ignition coil packs.

Check the inertia fuel shutoff switch in your trunk. It's designed to shut the fuel pump off in case of an accident. You haven't gotten bumped in your driveway lately? There are several other things it could be but, they are remote. ~Dave~

I'm pretty sure I'm getting pressure to the rail. When I pulled the spark plugs out, they were covered in gas. So i'm thinking it might be a no spark. But I didn't do a spark test, cuz I'm the only one here at the moment. My wife doesn't comprehend how to use the clutch, so she can't start it, and she doesn't trust me enough that the engine won't blow up while she's looking for a spark!

Where is that 30 amp fuse at? In the fuse block next to the hood release?
