Engine Performance problem
1985 Ford Tempo 4 cyl Two Wheel Drive 132000 miles

1985 tempo been sitting a long time will start with small shot of starter fluid. After it will only run while you pump the gas, this can go on for as long as you pump the gas, but try and hold it at any rpm and it dies from lack of fuel. It has the throttle body single point injection and the throttle body has been rebuilt the injector checks out OK, the fuel filters have been replaced, the fuel lines were blown out and the fuel drained and replaced with fresh. All electrical connections have been cleaned to the best of my abiities. So, what do you think, is their a computer in this thing? I'm just not sure where to go from here.
Thanks for any input. Peter

Ya, there's a computer. I think it's above steering columb on left. That's where it is on multiport! Nice thing about throttle body is you can remove ducting and watch it spray while cranking/running! And water pump is easier to change! Way easier! So have you watched it spray? Is it a perfect " cone" shape? I think it pulses while cranking but once running it's steady shower style cone. Any noticed irregularity means something aint right! Have you checked fuel pressure? Map sensor? Computer temp sensor? Tempos are not notorious for bad computers but age and miles definately play a factor there. Might be hard to find in boneyard? Maybe out in the boonies? Also make sure you have no vacuum leaks. Take a compression test on the cylinders also.
