That will work for a bit, but you'll have hot start problems soon enoughFriar said:I just had the same problem. It was resolved with a new battery, the old one was only 2 yrs old but wasn't holding a high enuf charge... warranty replacement!
With the 99.5's the pump in not the problem (although it can be), it is a well known software problem that is responsible for the hard start when hot issue of the 99.5s. The resistor tricks the ECU to fix/avoid the ecu, but if set-up right the resistor does nothing except when the car is being started.andy198712 said:A derv specialst surguested fuel pump to me was a normal cause for this in most diesels...
They are suggesting model specific code, not just an EU ECU....andy198712 said:mine does it, and its fixed if you unplug the temp sensor, BUT i have the EU ECU, so just saying, fitting an EU ECU wont fix the issue.
if that was what some people were surguesting
You need a switch that has a N/C and N/O contacts. One side of the resistor needs to go to ground to the ECU reads the resistance
Everything is good with this except the resistor needs to be grounded for the ECU to read it. I made that correction on my car works great.I was trying to use your drawing and instructions in combination with the drawing by MCathcart of the Hamman mod on this thread (post #316):
Hard to start when hot issue...
Unfortunately, besides your using a Bosch-style relay and MCathcart using a Radio Shack ice cube, the wiring also seems to be different - you run the resistor from Normally Open to Common, while MC runs it from Normally Open to Normally Closed.
These may be trivial differences, but since I have a pretty weak grasp of auto electrical systems and relay terminology, and I also wasn't sure about where the starter wire would be found, I had to abort my planned mod this past weekend.
I was wondering if you or another knowledgable member could provide some more specifics to help the more ignorant among us. Now that I have a Bosch instead of a RS, I'm ignoring the MCathcart diagram altogether. Having placed your 5-step instructions next to your diagram without confusion introduced from the other diagram, it makes much more sense. However, I need more detailed instructions on steps 3 & 4:A. How do find the starter solenoid wire? (Visual descriptions, references to Bentley, Haynes, or ETKA all acceptable)
B. Where would I find "a good ground"?
C. What is the preferred way to tap into the starter solenoid wire?
And one last question...does intermittent failure of my dash engine temp gauge have anything to do with this, or does it just mean that my blue coolant temp sensor is 3 years old and putting in for retirement?
I would like to know more about why the resistor needs to be grounded before I proceed with the relay modification below.Everything is good with this except the resistor needs to be grounded for the ECU to read it. I made that correction on my car works great.
