Anybody a 2.5 expert???? - 12/02/15 01:29 AM

2000 Sebring 2.5 I replaced all the timing stuff and a few bent valves. Went to start it after I got it back together, now I have no fire. I have fuel and 12 volts to the coil when cranking but there is no spark what so ever. Any help would be awesome thanks!

Oh and I put a new distributor in it.

Didi you put in the dist after or before the no spark? I have seen the factory ones go bad and the aftermarket ones be bad on install.

Might help if you ran the codes and told us what the computer thinks is wrong.

Put the dizzy in after the no spark issue came up, no change with the new one.

There aren't any codes.

I've narrowed it down to the comp now, I'll know for sure tomorrow. But I appreciate you guys responding to me.

Check the ground esp to the controller. I don't think the computer failed retrace your steps before you spend

Everything works except the dizzy. If it was a bad ground wouldn't everything the ECM controls not work??

Sounds like a defective new dist, but the dist is only telling the computer the dist is turning, the computer signals the coil to send out the spark. You should be able to check to see if the computer is receiving input from the dist, a broken wire between the computer and the dist will cause the dysfunction.
The computer receives information from several different sensors. A bad ground can interfere with the computer getting the correct signal from any of those sensors and the computer won't send out the spark. The computer monitors the oil pressure, the throttle position, the crank position the cam position and something evading my memory right now. It controls the fuel pump, the timing, the spark and how long the injectors are open.

I would start by making sure all the connections are making connections. Be sure the dist is turning. Be sure the timing gears are correctly lined up, then find out which wire on the computer receives input from the dist and see if its receiving the input. Its not unusual for the wires in the engine harness to break near the connections.
If nothing shows up after that come back and we will move on. Gene

sounds like the timing belt broke and wiped out the valves? you pulled the heads and replaced the valves? then no spark? how about the crank sensor , did it survive? do you have injector pulse? did you plug everything back in? that's a huge job tearing down that engine go back over everything. It was running when it broke the belt so....

Idler bearing went bad and jumped time on one side, it only slightly bent the intake valves on the one side. I was gonna go back and verify all sensors are good today, but as it happens that will have to wait until tomorrow.
But I have fuel/injector pulse and power to the coil so I know the ASD is not triggered by a bad sensor. The problem is somewhere between the comp and the dizzy.
Like I said before the problem is exactly the same with the stock dizzy and the brand new one so pretty confident it's nit the problem.
