93 Idi wont start

Hi

I have a 1993 F350 Crewcab Dually and it has 236K on it. It has trouble starting when the engine is not warm. Even with the engine warm it takes it awhile to get it started. I have replace the glow plugs and they are working. The light will stay on for about 10-15 seconds and then it starts clicking. It has new return lines with caps and orings. I have also placed a clear line to see any bubbles and there is nothing even after sitting all night. If you plug in the block heater, it still takes it awhile to start. It doesnt matter if its hot or cold outside. The starter seems to turn over nicely, it shows about 150-200 RPMS on the tach. The batteries seem to be fine to. I run waste motor oil and diesel but the problem started way before I i started running the oil. It has a new lift pump also.

Any suggestion would be appreciated.

Check or change the glow plug relay. My 94 had the same problem with being on for 10-15 sec. After i changed it the light stays on now for 30+ seconds. Thats where I would start, and make sure all of your glow plugs are working as well.

I live behind the Methodist Church by Gun World. I live in the culdesac that runs beside the park. My fiance drives the truck and she works in Slippery Rock. She works at the house across from Truevalue. The relay I think was like $80. It just looks like a starter relay to me.

Cool...I know exactly where that is. When you get the new relay get the Ford one. My one from advance took a crap and now im out $85. The Ford one costs that much anyways...Jerry Taylor has them in stock. When are you there? I may stop down next week sometime...Let me know.

i was having a similar issue, on my 95, it is a psd but still close, the issue i was having was fuel related, the mechanical fuel pumps arm was worn down and was not pumping enough fuel, it was fine after i got it running, but it would not build enough pressure when cranking to fill the resivior. its a PITA to get to on my setup but im unsire about yours, if its easy enough just remove it and inspect the long arm coming out of it and see if it is worn down any, and if not reinstal, and your only out the time it took to inspect the pump, balso see if your HPOP is building the 350+ psi needed for the injectors to squirt. i am not familiar with the IDI but if there is any sence to what im sayibng, i hope it helps you.
