My daughter has a 190e that started back firing. In looking at it I found that the distributor cap had a problem installed a new cap an rotor. Here is where the trouble started. Since it had been running a bit rough, I decided to install a new Idle Control Valve that I had kicking around the garage. I also had new rubber hoses to attach to the valve, so I replace the rubber while I was in there. I also installed a new set of plug wires and plugs (I don't get her car often so I do all I can when I get the chance)

Results - Car stared and Idled like new. However there was no power. When I depress the peddle, the rpm go up, but the transmission does not respond. It goes but barely.

(The power issue is, I think the vaccum line to the transmission. Tight quarters under the Idle Control Valve for replacing hoses. I think that I somehow pull the line out of the transmission)

Next morning, it started once a bit hard and then would not start at all?

1. Fuel Pump Relay is good (checked with a spare backup)
2. Overload protection relay is good (checked with a spare backup)
3. I am getting Gas, pressure regulator is ok. (checked with a spare backup)

This makes me feel that the Fuel Pump Relay, OV Protection Relay, Fuel Filter, Fuel Pump & Fuel pressure regulator are all working. Must be on the spark side? But I replaced the Distributor, Roter, Wires and plugs.

It tries to start but does'nt quit get there. If I push the peddle to the floor, it almost starts. I pulled all the plugs and they seemed oily. I cleaned and reinstalled. No sure why they would be fouled. Still no start.

Any ideas on what I can check. Like I said, I am getting fuel through the pressure regulator and the fuel line is pressurized. Could I have lost my coil coincedetally or perhaps was it going all the time?

P.S. I did check to see if the vaccum line to the transmission was holding and it was not. I replace the line and rubber and it is holding vaccum now, if I could only determine why the engine wont start I could see if this was the power issue.
