Yea, another "won't start" thread

Sorry but I've read the others and the same circumstances don't seem to apply.

I drove my car to work today- first time it's been out in over a month. It drove in just fine. When I went to leave, the car wouldn't start. I popped the hood, pulled off the air cleaner housing and cranked it over. I've got a fuel pressure gauge and it shows pressure is normal- pressure rises when key is turned to 'on' and drops if the car doesn't start within xx seconds. But I notice there's no spray from either injector while cranking, further- both throttle plates are bone dry.
I had the car towed and tucked it back into the garage. Oh, oil pressure gauge at least showed pressure while cranking. I checked all electrical connections.

Good suggestions?

Appears to be a lack of injector pulse.
Confirm that by using a noid light.

Do a search on here ,there is a multitude of " no injector pulse' threads with fault finding advice

Re: Yea, another "won't start" thread-update

I had the car towed home last weekend and I went to start diagnosing the situation yesterday. Thing started right up. Now I'm nervous about driving it again unless I can figure why it 'no started' before.

Several hours had passed from the time I turned the car off until I tried to start it so high temp was not a factor.

Anybody got anything? Please?
