Longer crank after sitting and shift issue

[Bunger317]

Picked up a 94' 4x4 single cab with the 4.0/a4ld combo. Great truck, 65k original miles. Only two issues I have is that 1. After sitting all day or all night the initial crank is about 3 times as long to start as it is when it's warm. I initially thought fuel pressure. 35psi with the key on 30 while idling. Pressure varies with throttle which leads me to guess the regulator is working. It won't hold that pressure over night but will for about 4-5 hours. Even if I cycle the key 3-4 times before starting it doesn't help. Don't think it's ever had plugs or wires replaced so I will be doing that but not convinced that's the problem.

2. The shift from 1-2 leaving a light or stop sign is pretty hard. Doesn't matter if I'm in drive or OD. If I standon the skinny pedal from a dog it shifts smooth but normal driving it's pretty stout. Check the governor vacuum line at the manifold I didn't seeany sign of atf in it. All other gears shift smooth. Any ideas?

My 4.0 sits alot...and is weird. After sitting for weeks (on a battery tender), it will fire right up...but sometimes not

Then after I do drive it a bit, It will fire right up, or not....

Then after I let it sit, but not long after I drove it...it will again fire right up, or not...

Ironically out of all three scenarios, the latter is when it will mostly take a bunch of cranking and even some pedal to start.

Most often instant fire is when its been sitting forever.

Dont matter if I turn the key a few times to cycle the pump prime.

I suspect fuel pump is on its way out.

Now it blows the fuel pump fuse every time I hit the base transition of a hill climb...Got a stack of fuses until I figure it out.

Anyone?

Could be the spark plugs
After sitting the engine is cold, so computer runs Choke Mode when starting, which is a RICH fuel mix, weak spark and too wide a gap would make it a hard start
Assuming fuel pressure was OK


1994 A4LD only has 2 solenoids, TCC(converter lock up) and the 3/4 solenoid OD shift
1, 2, and 3 are all valve body springs and balls and the vacuum modulator, no computer control

Someone may have put a "shift kit" in it, it does make for "positive shifting", lol, no slipping at all
