I am trying to get the car listed above back on the road. It has been sitting approximately 3 years. I removed galvanized fuel tank and pressure washed. There was a couple inches of black gunk in the tank. I replaced the fuel pump and bought a new OEM fuel filter. When I initially put fresh gas in it seem to start and idle fine. I only drove out of my shop and back in a couple times to move it. I filled the radiator a day ago and when I tried to start it it acted like not getting fuel. Which I didn't blow out any lines either. Then I put my code reader on to see two codes that were talking about coolant temperature readings were wrong from sensor via coolant temperature. And that the thermostat was open. I could almost start it and when it would I had to pump the accelerator like crazy. Thank you and any help is much appreciated. Eric, Route 66 Oklahoma

Hello,

Okay, so let's check the fuel pressure. In the diagrams down below I have included instructions for how to test your vehicle's fuel pressure. I have also included the fuel pressure lists for your vehicle as well. You will need to use a fuel pressure gauge, and you should be able to rent one for a deposit at an auto parts store, like AutoZone, if you don't already own one. Please go through these guides and get back to us with what your vehicle's fuel pressure is and we can go from there.

Thanks,
Alex

Welcome to 2CarPros.

A bad coolant temperature sensor can cause it to not start. The sensor provides coolant temp info to the computer. In turn, the computer adjusts the air fuel mixture based on temperature. So, the first thing I would do is using a live data scanner, confirm the sensor is indicating the correct temp. If it is way off, replace the sensor.

Here are the directions for replacing the sensor. The attached pictures correlate with the directions. Also, make sure the connector at the sensor is in good condition, free of corrosion.

2. Remove the engine coolant temperature sensor.

Installation
1. Install a new washer and the engine coolant temperature sensor onto the engine.

Tighten to 18 - 22 ft-lb (25 - 29 N.M).

2. Connect the engine coolant temperature sensor connector.

3. Start the engine and check for coolant leakage.

Do this and let me know what you find,

Take care,
