91 Formula 305 tbi.. Sat for a month. Went to start and nothing but cranking.

New ignition control module and ignition coil, plus a new fuel pump relay.
Motor cranks, but doesnt start. I see no fuel spray from injectors and with starting fluid, nothing.

What should i do next? Car ran just fine a few weeks ago !!!

 

Thank you in advance for any help !!!

 

Is there spark? A check engine light? If both spark and fuel are out I'd assume a bad ecm or a bad connection somewhere.

 

Have you checked if you got spark? .. if not, then I would stab me a screw driver in 1 of the spark plug wires and have some one turn the engine over. if you get shocked then. yeah you know the deal.

 

Havent checked spark since replacing ignition control module and coil . I thought replacing that would do it. Not even so much as a start with starting fluid and new parts. Hope I dont have to drop tank for new pump and sending unit.

 

nope. you know. you could just need a tune up. (plugs,roter, wires)... if you said you tried using started fluid and it didn't even make a stutter to try and start then it aint fuel.

 

Thanks, I will try that.. Fed up is all, Never gave me a prolem since I bought it. Am the 2nd owner since 91!!'

 

Always test ( especially if replacement parts changes nothing) Never assume.
You may have screwed something up when replacing parts or got faulty parts.( not uncommon these days )

That is the big indication you have NO SPARK in the clylinder

A Ign system diagnostic work through like this can help identify where you have a problem
