No warning cut out

[Ameer Antar]

Just a thought: check your wires/connections going to the ignition coil, both the primary and secondary circuits. I had dirty connections on the low side cause stalls in my 5kT. It's probly worth getting a can of electrical contact cleaner and spraying any connections in the engine bay that are in rough shape. After 285k, I'm sure there's a few corroded connections even if you don't live in New England.

About the fuel pump not shutting off... That's strange cuz the fuel pump doesn't have a switch in it really. If you put power to it, it pumps no matter what. So replacing the pump shouldn't stop it from running all the time... It sounds like the fuel pump relay was doing something wrong... a bad relay, wiring or ECU signal. Maybe there's something going on with that circuit??  Also, what ECU codes got stored? That might give you some ideas.

good luck.

   Good morning,
   
   Yesterday, I drove down to Northern Virginia from South Jersey to pick up 
   some parts from a friend. I drove my 1987 5000cs TQ. MC1 with IA chip and AAN 
   wastegate. Other than that, it's stock. Everything driving down was fine, not a 
   problem to complain about. I was driving with the climate control set at ECON 
   just to circulate air. The cruise control was on some of the time and off most 
   of the time. All the windows were up and the sun roof was tilted up. Temp gage 
   was indicating normal/on the cool side. It was between 65 and 70 degrees. On 
   the way back, I had a major problem or perhaps, better said as a major hiccup. 
   I was on I-95 north, just north past Baltimore, MD. I was driving with 
   traffic when without warning I get nothing. Pressing on the GO pedal gets zero 
   response. Every light on the dash was on that would have been associated with any 
   other engine stall while at speed. Pressing on the clutch pedal brought the 
   Tach to zero, releasing let the engine speed indication return. The sun glare was 
   so bright, that I could not see my hazard lights on the dash going on/off. I 
   made my way to the right lane/shoulder and coasted as far as I could after 
   going about 75-80 mph with the traffic. I stopped under a bridge and tried to 
   remember if there was anything unusual before this happened. (a word of advise: 
   Never stop under a bridge if it's a nice day out. It was so noisy under there 
   with my car not running, I couldn't hear my hazard relay working or even if the 
   car was running) I closed all my windows and sunroof and tried to listen 
   closely at my attempt to restart the engine. It cranked but nothing was happening. 
   I let it sit for about a minute and I tried again and it started like nothing 
   was wrong. Not wanting to press my luck, I put her in gear and merged into 
   traffic under hard boost (1.8 or so) No problems at all for the rest of the 
   trip. Trouble shooting from my desk here, I can only think of a couple things. The 
   first being that the fuel pump cut out for some reason. The second, I lost 
   all ignition spark. I would like to rule out the fuel pump because it is fairly 
   new from the spring/summer of 2004. Maybe an ignition switch. May just a tune 
   up is needed, but that still doesn't give way to the abrupt cut off at highway 
   speed yesterday.
   
   Any idea's? I haven't done any real trouble shooting yet. The last time the 
   car had a real thorough tune-up was right before I left for Atlanta, GA after 
   9/11. The car just turned 285,000+ miles as of yesterday.
