I have a 1998 escort 2.0 SOHC engine that I just picked up. It ran beautifully, started right up, ran smooth (no misses or noises). On a short ride the other day it died (just quit) and it cranks over but won't re-start. I towed it home and have checked the following: Changed the timing belt (it wasn't broke but had some wear so I thought maybe it had jumped time - it hadn't as the marks line up perfectly on cam gear and crank gear), checked for fuel at the fuel rail using a pressure tester (have good fuel pressure and the spark plugs are getting fuel as after cranking for awhile they are getting wet with gasoline), checked with noid lights for injector pulse and is good, changed the crank position sensor, changed the spark plugs in case they were getting wet fouled, checked for spark and have very good bright blue spark at spark plugs using spark plug tester. What I don't have is good compression. All I get for compression is around 35 - 45 lbs. In each cylinder. I've checked for vacuum leaks by tagging into the intake lines with low pressure from my air compressor and can't find any leaks. I thought maybe after checking everything else I might have washed the cylinder walls with gasoline from all the cranking, so I injected some oil into each cylinder and re-checked the compression and it was still low with no significant improvement (5-10 lbs. Maybe). The car ran so well before this that I can't believe it had this low of compression and I think the low compression is why it won't start now, but what could cause a sudden loss of compression on all cylinders, yet the timing is o.K. I've also pulled the valve cover off and checked the cam to see if it was rotating and the valves were moving and they were (thought maybe I had a broken cam). I can't thing of anything else to look for. Any ideas. Thanks.
have the same problem?
