Hi, Seat Toledo 1996 occassionally cranks, fires,

wont reset until repair have problem with throttle body position sensor /circuit repair problem https://repairpal.com/obd-ii-code-p0121 https://www.yourmechanic.com/article/p0121-obd-ii-trouble-code-tps-a-circuit-range-performance-problem-by-jay-safford

Fuel pump intermittent, check for fuel pressure before dropping the tank to renew pump.
Otherwise check electrical connection at battery, and make sure you do not have an open circuit.
Loss of connectivity could cause this issue, failed fuel pump sometimes work, but are not reliable.
You should see 30-45 psi at fuel rail, and the regulator should bump pressure 5 psi when reving the motor. Higher pressure indicates failed regulator.

Try to check if some fault code is stored there, try self scanning the PCM (turn on, off, on, off, sna finally stay in ON ignition switch), note the codes in the odometer and sens ud details.

Keep in touch.

Attached is link to Rave Manuals (Rover Bible) BTW yours is listed as Discovery (not 3 if it's 1996) These have exploded wiring diagrams & pics - http://www.landroverresource.com/

Hello,

Were you able to fix your problem? I'm having the same issue with my car, where the Odometer intermittently jumps from 0-48. At times when I start driving the engine stalls and the Odometer starts to act up. The Egine Light is always on. I would appreciate any help.

my 5.7 is equipped with a cam sensor, a device that senses the motor turning and times the injectors to the firing order. if you do not have a code reader, or a diag. tool, then i'd suggest dragging it to a shop that has one. some things are easier to pay for than to do, if you don't have the right tool.

May have to get a code reader for this one..... Bad coil, open wire on crank shaft sensor, fuel pump, are among possible problems..... Try a bit of starting fluid, not much of too often mind you!

1996 EXPLORER This TSB article is being republished in its entirety to include the 1995 4.6L Thunderbird/Cougar. ISSUE: After a 1-4 hour engine soak time, long crank times and/or long crank to start followed by a stall may occur on some vehicles. No further stalling or rough idle will occur after the engine is running. The long crank and/or stall may be due to the Idle Air Control (IAC) Valve sticking.
ACTION: Replace the IAC Valve with a revised IAC Valve if no Diagnostic Trouble Codes (DTCs) are present. Refer to the following Service Procedure for details.
SERVICE PROCEDURE

1. Perform normal diagnostics and correct any DTCs as required by referring to the appropriate year Powertrain Control/Emissions Diagnosis (PC/ED) Service Manual.
2. If no codes are present, replace the IAC Valve by referring to the appropriate model/year Service Manual, Section 03-14. Refer to the following Idle Air Control Valve Application Chart for proper IAC usage.

First off you can test the fuel pump 2 ways
1.have a assistant turn on the ign to on while you listen for the pump to run at the gas cap (gas cap off).
2.find the valve on the fuel rail looks like a a/c or valve stem,take the cap off and press the needle and if fuel comes out then it's not the fuel pump.

But from a lot of EXPERIANCE on dodge engines the stalling and restarting issue is ignition related i.e crank or cam sensor which will throw a diagnostic code of engine misfire xxx cylinders.

So If its one of those sensors then you will not have any spark,and staring fluids will not fire the engine.
As for the headlights flickering they get there power through a relay straight from the battery,so I would look at the relays under the hood and find the one for the headlights and swap it out with the horn relay as most of the relays will have the same numbers.

The crank sensor is about 70.00 and the cam sensor is about 50.
depending on where you get them (dealer or aftermarket)
the cam sensor is the round plastic thing under the dist cap,and the crank sensor is on the pass side under the head into the top of the transmission bell housing and it's a 2hr job to change because of it's location is really hard to get to.
Hint -take the breather off and place a rag over the intake and a board from the radiator core support to the intake to lay on,it has 2 10mm bolts and the wiring harness unplugs from underneath.

if the fusebox is above accelerator pedal its relay number 1 .best of luck.
