Full Version: Tis the Season for HOT START trouble

All,

Lots of threads about FORD relays (really?, would not any starter relay work) but this trouble is different.

In the manual, it says to hold the accelerator pedal to the floor when starting a DJet, so I tried this.

I would like to FIX this so I can start when the car is hot like a normal car (yea, I know it is not a normal car), has anyone made a modification to the instrumentation to fix this issue?

Perhaps CHT modification?

Hot start or djet components ( acting cranky )
Not impossible but any djet issue very hard to find let alone fix .....

Just to be clear- the Ford relay solution is for the starter not cranking when hot problem. As you say, this is different.

The next place to look is vapor lock. The early cars had the fuel pump in the engine compartment, where it would heat soak. Moving the pump to the front (as the factory did in later cars) usually solves that problem.

If you’ve done that, then you’re left to figure out which component of the FI is being cranky. Others will have to chime in on that... I’ve had carbs since the 80’s (and I moved the fuel pump up front). My problem is more with cold starts in the spring and fall!

Good luck.

Other than actual vapor lock which I've never experienced (my pump is on the lower firewall), but from a D-Jet perspective Brad. Anders posted something here a couple of years ago where he surmised the issue is that the car is excessively lean during a hot restart. He was playing with the idea of using a variable resistor on the CHT that you could control from the cabin. I can't seem to find that thread jsut now.

In my case the issue was usually that the car was somewhat difficult to start and I had to feather the throttle for about 30 seconds before the idle would stabilize. What really helped me at least from the starting standpoint was using the hi-torque starter of all things.

I will reach to Mr. Anders (Mr. Djet) and see what he recommends.

Will close out this thread with some discovery. ASAP
Thank you

Does it seem that it wants to catch if you release the key quickly (from the start to on position) when trying to start it? If so, your switch is broken. Also, check the voltage at your coil when cranking to see if you have 12v.
