No Start Without Using Starting Fluid

[snakedoc67]

Trying to diagnose a crank but no start condition. It will start only with using starting fluid and until it runs for about 20 min to warm up it will surge and die when in gear and the gas is pressed. I had the clutch replaced last week, prior to taking it into the shop it would start normally but still had the stalling and lack of pep. The fuel pump is the main suspect but since I won't be able to afford a new one for a few weeks trying to find other things to check first. I can hear the fuel pump running when the key is turned to start, and I get fuel from the rail when doing the poor man's fuel pressure test. I will be "borrowing" a fuel pressure gauge from Oreillys to try and get an accurate pressure.

 

I pulled the fuel tank from my parts truck earlier this summer and it should have the pump in it still- is there a way to bench test before i go thru the process of installing a bad pump? Also, is there a way to rebuild them other than just the filter on them? 

 

Things that have been done recently:

When the clutch was replaced I verified they took out the CPS first, I also had them replace the master cylinder and hose, as well as converting it to DOT-5. The mechanic had powerwashed the bottom of the Manche when they replaced the clutch but stayed away from the coil and relays, he also pulled the cap to make sure there wasnt any water in it. 

The fuel filter was replaced earlier this summer so it should be good. I also refreshed the grounds at the oil filter post and the left rear taillight a few months ago as well. 

I replaced the MAP sensor to the throttle body line yesterday. (it broke when i took it in but didnt seem to make a difference to the starting). 

 

Not done yet:

Have the parts just havent installed them- New TPS, new spark plugs and wires, new grounding cable for the firewall to engine block, 

C101 connector cleaning was started but only halfway finished.

I believe that the "to be done" list will likely solve your problem.  Mostly the TPS, but all of those things are good.  Follow Cruiser's TPS tips for ease of handling.  I also did the "Sensor Ground Upgrade" in his list of things to do.

Might not be the pump itself, but the hose inside the tank that goes to the pump.

I should find out today (monday) when I pull the sending unit out of the tank. If its bad the sending unit from the parts truck looks ok. Just have to wait for the locking ring Oring to show up at NAPA today.

Pulled the fuel sending unit out and found the internal fuel line loose. Replaced the fuel lines and filter and the no-start/lack of power is gone. Also disassembled the throttle body and cleaned it and the IAC.

Awesome!  Glad it's fixed.
