Hi I have a no start problem that I dont seem to figure out. It is a 1995 K1500 6.5TD. it has been standing without batteries for a little over three months and when I now put batteries back in and went to start it wont. It cranks good and after about 4-5 seconds sounds like it is about to start but nothing happens, get white smoke when it is trying to start so looks like it is getting fuel.
Checked and cleaned all grounds, checked all plugs and wires.
Have checked the glow plugs and all checks out with a testlight.
Tried with and without the optical sensor attached, no difference.
Took the stop solenoid out and tested and it is working.
Checked the lift pump took the hose off the intake on the IP and put in a bottle and it fills a 42oz bottle in just under a minute, attached a clear hose to the return from the IP and I barely have fuel coming out here, took about a minute to fill the clear hose in the picture up to the top, and dont have enough flow to keep the downside filled.
Is there something else that might be a problem with my IP or isnt it supposed to let more through when its not running.
What else should I check?
