Re: Car will not start.
 

Might be helpful to know more about the engine type, ignition type, distributor, etc. Does it crank over but just not start? Have you removed a plug wire and have spark at the plug? Checked the rotor and cap? If you have spark at the plug, it must be fuel related. Years, many years, ago a guy taught me about engines. There are three things that every engine must have, air (he breathed real deep and confidently said that there was plenty), fuel (pumped the accelerator, and fuel came out), now just needed spark. If there is fuel, air, and spark, then maybe a timing issue. Does it crank over smoothly?

Dan, Yes to all your response.

Re: Car will not start.
 

Dan: 4 things, spark, air, fuel and compression.

Re: Car will not start.
 

Thoughts;

Do you have access to live data with an onboard display or controller?

If so, check that all sensors are showing a normal value.

*Ambient air temp correct?
*Coolant temp correct?
*TPS correct?
*MAP correct? [connect a vacuum source to the MAP, it should show a voltage range with different vacuum levels applied]
*Fuel pressure correct?
*Are the injectors pulsing? [check with noid light tester or "listen" for the injector ticking with a listening device]

Here's a update. It has no spark or fuel.

Re: Car will not start.
 

With that information, check for power and ground to the controller

Re: Car will not start.
 

We are checking the ignition panel now.

Re: Car will not start.
 

Your issue appears to be the big stuff is not receiving engine position information (no crank sensor input) not familiar with their stuff but I'd think they would have an LED somewhere on the box that blinks each time it sees a crank sensor pulse. No pulse equals no spark or injector activity.

Re: Car will not start.
 

Are you running any kind of start retard or "starter saver" box on this car? I had two different MSD retard modules - the cheaper ones - kill the ignition on my series 8 box.

Get a multimeter if you don't have one and trace power back from the contacts on your ignition box.

No rpm displayed on the tac indicates issues with the component that sends that signal. Did you change out your ignition box?

Good luck. I could have written this thread this Spring. Multiple ignition failures after big changes under the hood.

We are still plugging away and now we are running wires down.
