Hello,

I have a 92 civic dx manual with 220k miles
It overheated about a week ago turned out to
Be a bad thermostat and it cranked right after I fixed it
But the next day
The engine cranks over but it won’t start.
I got no problem codes.
Check engine light never came on.

I Checked and replaced fuel pump relay no fix.
I Checked and replaced fuel pump no fix.
I checked and replaced distributor no fix.
I've done the K- test at the map sensor and only got 4.9 volts
Do you think it's the ecm I really am just getting frustrated

Preliminarily, I don't think your ECM is the problem, since you recorded 4.9 volts.

. Test all under hood and under dash fuses with a test light or multimeter:

. Clean the main ECM ground, located on the thermostat housing. Look for a 3-wire brass connector.

. Replace the CEL bulb, if it still does not come on. Perform the tests in the link below:

Well I found out why it wouldn't start turned out I was out of gas but now that it's running again I have yet another question... see my fans not cutting on and that's got me worried what do I need to do about that...

Truly appreciate all your posts they were quite helpful. I put a new switch on checked the fan and relay they both work I think what I did was when I flushed it I got too much air in the system I'll have it reflushed by a professional come Friday... thank you for your help once again truly do appreciate it...

Also I have a question about my engine knocking more now that it's overheated... and also when I start in first it feels like it's bogging out when I first get started going and then when I get probably around 3000, 4000 rpm's it stops doing it... once again thank you for all your help...

Only refill with a 50/50 mixture of Zerex G-05 antifreeze and distilled water. These links will explain why:
