Long crank, no faults
Realized that I didn’t look at the voltage when the car was cold, checked it again right after I started the car and this is what my voltage read. However after driving for about 5-7 mins the voltage went back down to .6ish. Would this mean I still have a bad sensor?- Jimmy Brooks

Yup, that would do it. Hopefully it’s just the sensor and not a wiring issue. Do I have to remove the intake manifold if I go to replace the sensor?- Jimmy Brooks

@jlglr4 On temp sensors 1 I’m getting a reading of only .6 volts while on the other sensor I’m getting 2.4 volts. Is the temp 1 sensor a 5V sensor? Because normally the 5V sensors are supposed to sit between .8-4V. Just thought it was weird that it wouldn’t throw a code for low voltage on that...- Jimmy Brooks

Car has been in an insulated garage for the last 2 days and it’s cold started perfectly normal 3 times in the garage. Think it’s gotta be a temperature thing. Which temp sensors in the engine should I check that would affect a cold start.- Jimmy Brooks

Which temp sensors should I check. I checked the fuel rail pressure voltages before all this and they looked good and changed voltage when engine rpm is climbing.- Jimmy Brooks

Intermittent burning smell?
I still get an intermittent burning smell while I have the heater on but I’ve always had it for as long as I can remember so I assume it’s just the heater. Since I live in California I only notice this in the winter. some times I’ll notice it after I get on the gas a little and I assume that my...- Jimmy Brooks

Long crank, no faults
Interesting… yesterday I watched it crank and build pressure slowly to 2000psi during the first crank. Turned right over on the second one but the rpm went straight to 1500 rather then going up to 2000 rpm on start then doing the warm up idol 1500 rpm. Today I did a cold start after 5 hours of...- Jimmy Brooks

And as for hearing the low pressure prime, I only hear it if it’s extremely silent around me. Most of the time I don’t hear it tho- Jimmy Brooks

Is it jumping to 14000kpa while cranking or right after starting during high idol?- Jimmy Brooks

Looks like what I’m observing is pretty normal then. Is there a live value for the low pressure fuel pump that I can see? Is it possible it’s not priming enough? would that make sense even if it was driving perfect apart from cold starts?- Jimmy Brooks

Now that I think about it I might have been smelling a little bit of exhaust and mistaken it for fuel upon first start up. Do you think the 40psi difference would be enough to make the difference of a 3 second crank and a 10 second crank? Or do you think it’s not fuel system related? Starter...- Jimmy Brooks

No. Heres the whole run down, when the car is idoling normally fuel pressure fluctuates from 418-425 psi. While the car is running the “fuel rail pressure desired” reads 0. Only when the car turns off does it desire 1450 psi which tells me the car is supposed to build to at least that amount of...- Jimmy Brooks

Ok so over the past couple weeks I’ve been able to narrow it down to a leaky fuel rail. Every time I open the driver door I hear the low pressure pump prime and the car has no trouble while running or driving (doesn’t stall no hesitation no weird misfires) so it can’t be high pressure either...- Jimmy Brooks

When I turn off the car the fuel pressure tends to build up a bit but by the time I get into it aftwr it’s been sitting for a while the car only has 50ish psi of pressure- Jimmy Brooks

I can tell as time goes on it’s getting worse, every time I leave the truck out side for over a 3 hour period of time the truck cranks for 4ish seconds in 61°F weather. Still couldn’t find any low pressure fuel pump live values. Any other suggestions on how I should track this issue down. Do you...- Jimmy Brooks

Not sure, couldn’t really find a live value for the low pressure, only the desired. Is there one under a different category or one that I missed that will show live low pressure data.- Jimmy Brooks

Long crank, no faults
Ok so came back to the car after letting it sit and the first thing I did was check the live values before starting the car. With the battery on I was able to see that my current fuel rail pressure after letting the car sit was 53.7 psi while the desired fuel pressure was 1450 psi. When I...- Jimmy Brooks

It’s just odd. I was up in mammoth for a couple of days while it was 20 F and the car started fine the whole trip. Yet when I was up in Santa Clarita aftwr it rained it cranked for the longest time and finally turned over. Just did it again this afternoon after it had sat for about 5 hours. I...- Jimmy Brooks

Co is there anyway I can check and confirm with live values on IID tool? No smell of gas ever though.- Jimmy Brooks

It’s not slow, I’ve heard it crank faster but it’s not slow to where I think it’s a battery issue. It’s more of a medium speed but a normal health speed given the lower temperatures.- Jimmy Brooks

Could be. I did notice that in below 32 F weather that the voltage would not go up from 12.2 V aftwr starting the car until I pulled away and RPMs were raised from idle. Today it wasn’t particularly cold, it just rained all last night and when I started the car for the first time it was probably...- Jimmy Brooks
