Hello to all and hope that someone can help me. I know this is long, but I'm at wits end! I changed the water pump on my '92 940 turbo, put it all together and no start!? Now she just cranks with no ignition. Started just fine before the water pump change and can't believe the change of a water pump led to this...anyhow, I went ahead pulled the upper timing belt cover off again to verify the timing marks...how it would have changed by changing the water pump I don't know but figured what the heck. With the timing mark lined up on the balancer to the mark on the lower cover, the camshaft gear mark was lined up with the 12 o'clock mark on the inside of the timing belt cover so we're good there. It was time for a tune up so I went ahead and changed the cap, rotor, plugs, and wires since I had them already still no start so went back to troubleshooting. I checked the coil and between terminals 1 & 15 read .7 ohms, between 1 and the high-tension terminal read 7.82 k-ohms. Disconnected the fuel line to the fuel rail with fuse 11 removed and cranked the engine to verify operation of the main fuel pump and had plenty of fuel. Disconnected the Crankshaft positioning sensor at the connector on the firewall and read between pins 1 & 2 and got 176 ohms, the book says it should be between 200 - 500 ohms, but research of others who took readings were in the range of 160 - 200 with new units, so I'm assuming (hate that word) mine is okay. I then checked each fuel injector for voltage and got 12 volts at each. Okay, so that was all the book stuff, then I did the old school checks; easy spark test by pulling each spark plug keeping it connected to the distributor wire and grounding the threads and had spark at the electrodes on all 4 plugs. While the plugs were out, I had a friend crank the engine and held my finger over each hole and had fuel...also, while the plugs were out, I pulled the fuel pump fuses and did a compression check on each cylinder with the following results: #1 cylinder 110 PSI, #2 100, #3 108 and #4 105. So, got spark, got fuel, got air, got compression...no start! what the hell am I missing???


Okay, so now it is 5-days later. I was starting to think that it may be the Ignition Power stage amplifier, thinking that even though I had spark, it may not be “hot enough.” But as a double check I got my hands on a timing light, cranked the engine on each wire and the light pulsated with each, so I'm assuming (there's that word again) that I'm okay on spark? So here we go again, triple checking, I pulled fuse #11 so I was only using the main fuel pump, disconnected the fuel line to the fuel rail and cranked the engine; I got 20 ounces of fuel in 10 seconds so I got fuel. Checked the injectors once again and had 12 volts on one terminal on each and was getting between 230 - 270 millivolts on the other terminal, is that normal? I then checked the red lead on the Auxiliary Suppression Relay and had 12V. I then checked the gray wire from the Suppression Relay and had 12V, then I checked the gray wire at the Ballast Resistor and had 12V as well as 12V on each of the 4 green wires coming from it. I'm at a loss here. When my wife gets home from work I'm going to have her crank the engine for me while I see if I can tell if the injectors are operating (clicking?)...Although last week when I had the plugs out and with my finger over the spark plug hole my finger was getting wet with gas...and you could see a "mist" of fuel as well blowing out from all the plug holes. While I have my trusty assistant for cranking I'll also hold the timing light on the timing marks while she's cranking to see what I got...other than that I'm stumped. Unless anyone has any enlightening suggestions I may have to break down and bring it to a shop...I can't believe I just said that...
