Seve12345 you were right there 5 days ago. If you had only checked the ignition switch output on that blue wire, you would have been driving a lot sooner. Anyway good job.

Hey I hope the guys who helped this fella are still around. I have a 94 escor with a 1.9 liter and have a crank but no start condition. I have check all the things you instructed th o.P. To check and have voltage on the blue ignition wire and my relays click and have continuity but still no spark at the coils, brand new coil by the way. I'm leaning towards the computer as the issue, how do I continue from here, please help?

Hello,

Can you hear the pump come on in the fuel tank for five seconds when the key is turned on without cranking the engine? Here is a guide to help you get started:

I've done all the guides said to do, I definitely do not have spark. I have a new crank sensor but have not put it in yet. The relay is absolutely good, I pulled it out and tested continuity through it and there is a click when installed. My check engine light comes on when key is turned as well. Have to go to work now I will check in later, thanks for the help.

I would do the crankshaft sensor first. here is a video that shows a similar car getting the sensor replaced:

I've already pulled the crank sensor and ohms it out and compared it to the new one and they are the same. But I will install the new one anyway and report back.

Yep, a sensor can still be bad even though it tests good. Let me know.

Changed it, but found the real problem. Internally broken spark wire, looked new but tested bad. Found the car has blown head gasket also though. So I will be doing a head, water pump, and timing belt. Thank you for the help.
