Besides wiring and the EGI fuse; what would make the primaries not fire while starting?

I have spark and till now I was flooding the car. (Did the unflooding procedures... many times.)

Now I do not think the primaries are delivering fuel because motor turns but when I pull plugs they do not smell like fuel nor does the exhaust.

Faulty FPR solenoid?

So is the car running or not? or are you just messing with stuff to see if you can make it break?

I will ohm them and shoot those wires ...thanks for reply
Yep, pump is runnin' Checked with jumper. Thanks for reply.
You raise an interesting point, I have an SX Regulator; do I pull it (FPR solenoid) or leave it alone?
NO... and Yes I break all my stuff for fun, let me know when you need some help

possible vapor lock, bubble in the line? interesting problem. I'd leave the solenoid alone until you can hone in on it as a problem. Don't want to break any solenoids if you can help it.

Maybe disconnect the fuel line to the primany rail and see if there is fuel in it. If so then the rail is getting fuel but the injectors might be bad/cloged/ect. Or there could be an electrical problem with the connectors that fire the injectors.

I got a resume cool!

Anyway, in saying it tries to start, does it go vrooom-blah? Or just sits there and cranks and vum vum vum vum vum and thats it?

LOL,

Earlier the car would fire more like... cough..cough.. cough (pretty repeatitive) with some smoke. Now it just spins with starter and has spark;
Spray some starting fluid and more cough cough cough some smoke till it burns all the fluid and then just spins.

How about pressing on the gas pedal when starting? nothing?

How about the EGI relay? I noticed you did say besides this, does that mean you changed it?

It is an interesting problem.....

Any possible way you can get a compression tester, its worth looking into, or just borrow it and start troubleshooting.
