Had a go at the wiring over the weekend and had a couple of issues. I got the engine to turn over but would not start. Checked fuel was being sent and that was ok, but read last night that the fuel system is pressurised. Does that mean I need to seal the tank ( will use the donor filler pipes) to get the fuel to feed through? Also read in the owners manual I should prime the fuel system to avoid over cranking the engine is this needed? As stock the fuel tank is sealed but not pressurised, it is vented via the carbon canister to prevent petrol fumes venting to atmosphere. It won't make any difference to the car running if filler is open (but will cause the Check Engine light to illuminate). The pump should run for a few seconds when the key is turned on to pressurise the fuel system.

Pressure line connects to the front of the fuel rail, to check which line is pressure put each of the lines from the tank into a suitable container and run the fuel pump for a few seconds, it's a good idea to flush the line before connecting to the fuel rail anyway.

Check cooling fan relay - right rear of engine compartment: BLU/YEL wire hot at all times from 30A fuse in engine compartment fuse box BLK/WHT wire hot with key on - engine fuse YEL wire - power to cooling fan RED/GRN wire - grounded by ECM to energise relay

Have you checked the fuel tank venting?

The fuel return line should connect to the pressure regulator on the rear of the fuel rail, the vacuum line should connect to manifold vacuum. If the pressure regulator diaphragm is bad the vacuum line can suck fuel into the manifold.

Unlikely to be timing belt, more likely to be a fuel pressure problem. I think the '90 MX5 has a pressure regulator in the fuel tank, a single line to the fuel rail and a return line teed into the fuel line near the tank. I don't remember a electronic fuel pressure regulator so the P1250 code is a bit odd.

The Arizona Sonic put away for the Summer: Back in chilly Wales, looking forward to driving the Sonic when we get back in October.

The purpose of the EGR system is to reduce NOx emissions, it does this by adding an inert gas (exhaust) to the intake and reducing combustion temperatures. In theory removing it will let the engine breathe undiluted intake air and improve performance. However, in modern engines the EGR is integrated into the engine management system fueling map and is also used to control ‘pinging’ or pre-ignition under load. On a 40-degree C day in Arizona climbing the 3000’ Davis Dam grade there might be a chance of melting a piston – with a lightweight Exocet in the UK probably not a problem! Bottom line - if IVA and MOT inspections don’t require the emission equipment to be intact you could remove the hard ware and blank everything off and install resistors across the solenoid connectors – the only advantage would be to get rid of some of the under-bonnet clutter. The same applies to the EVAP system, it is designed to trap raw fuel vapors in the carbon canister then burn them off in the engine via the purge valve, may help stop your garage smelling of petrol. Fuel pressure regulator does need to be connected – it controls fuel pressure relative to manifold pressure.

I think the reason for the front brake connections is that in event of a front brake failure the proportioning valve will allow full pressure to the rear brakes.

It's bolted on with 2 M6 bolts through the aluminium frame to the windscreen recess, actually seems quite solid, ran it up to 70MPH and it seemed OK. Don't think I would want to use it permanently, it has already 'fallen off' .

Congratulations John. I love the innovative "screen" not sure Angus will be offering that as an upgrade or accessory though. Have fun and keep safe. This is the third build I have used it on, strange ADOT requirement, an ATV or 3 wheeler does not need a screen but a 4 wheel car does

Yea,a manual wiper is acceptable, and the single seat was just for the inspection. It now has a Arizona licence plate: double roll raffle ticketsI've ordered a SONIC7 plate Is there a little spam going on here? Raffle tickets? Not sure where that came from - deleted it once but it came back, just tried again.

5.30AM appointment with ADOT inspector, passed no problems although the heights of some of the lights and reflectors were marginal. Arizona requires a safety glass windshield with wiper, this one complies but not well fitted it is likely to fall off . imghostNice cool (70F/21C) 30 mile RT drive - a few squeaks and rattles but ran well.

Maybe I'mm confused (not unusual) but I thought the 2000 MY Miatas had a single fuel line to the engine with the pressure regulator in the tank. I seem to remember working on a UK car that had that fuel system
