Installed Timing Belt and now wont start?Help

[philjw90SHO]

I know that this is SHOforum and I have posted here many times before and I really appreciate the responses I get so I was hoping some of the mechanically inclined people could help. I have a 1993 Mitsubishi Eclipse with a 1.8L SOHC and the timing belt broke WHILE my brother was driving it. We replaced the timing belt with a new one and tried to start it. But first I checked compression and it was even on all 4 cylinders which convinced me that there are no bent valves. Then I pulled the spark plugs out and checked for spark and there was spark. With the battery connected and ALL accessories includeing alt. disconnected we tried to start it and it turns over and nothing happens. It was at the shop on Friday and they told us the timing belt was broke. We had it towed to my house and then started working. I was hoping someone could tell me why it wouldn't start because while I was checking the compression the engine started briefly and then my brother shut it off. It acted like we used up all the fuel or something. The only things we took off were the accessories and the hood. When the shop called they said that it wasn't a fuel problem which makes me think that they did something to the fuel system and didn't put it back to normal. What could they have done or what could we have done to make it not start. We followed the manual on how to line up the timing marks and I'm 100% positive we lined up the timing marks right but it won't start. PLEASE HELP anybody who knows what to do. THANKS

Did you follow a procedure and align the crank and cam pullies or just stick the belt on? It's called a timing belt because it keeps the cams timed correctly with the crankshaft. Just because all cylinders had the same compression doesn't mean they weren't all affected in the same way. What was the compression and how could it be measured without a timing belt installed? How long had the old belt been on the engine before it broke? Way too long I would guess. Maintenance, maintenance, maintenance. It pays for itself by not letting you **** your engine. You should know that well by reading the posts on this Forum.

I agree with Scott not just on the maintenance but start where you left off- recheck the timing belt install to be sure everything is in spec. Is there a DSM procedure to be followed here? If all the marks line up is the sensor configuration similar? Did the broken belt break anything else in that area? If you suspect fuel is there a way to measure it near the cylinders to see that it is pressurized and is keeping pressure?
