92 civic dx won't start
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: https://www.askmehelpdesk.com/cars-t...tml#post252145 . 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: https://www.askmehelpdesk.com/cars-t...tml#post291477 |

Only refill with a 50/50 mixture of Zerex G-05 antifreeze and distilled water. These links will explain why: https://www.askmehelpdesk.com/cars-t...tml#post235973 https://www.askmehelpdesk.com/cars-t...ml#post1365453 |
