Why won't my Nissan Stanza start after sitting, or why won't it rev normally?

Short answer: If your Stanza sat for years and only runs on starting fluid, fresh gas on top of old isn't enough: members said to drain the tank, because old fuel can ruin the pump, and to confirm spark and compression. If it sometimes won't rev and surges up and down, these older computers are hard to read, so check for a code light, the fuel filter, and a faulty idle air control valve.

Symptom: After sitting about five years with new gas added, it cranks but only fires on starting fluid and won't stay running. Or the car usually runs normally, but sometimes revs climb and drop repeatedly and won't build speed.

What to check first

1. Drain the old fuel from the tank rather than topping it off.
2. Check whether the fuel pump runs and builds pressure.
3. Confirm spark and compression.
4. Look for a check engine light; on these OBD I cars, codes may not be readable by parts-store scanners.
5. Replace an old fuel filter and test the idle air control valve.

Likely causes

1. Old fuel and a gummed-up or ruined fuel pump. Members' first concern after years of storage.
2. Clogged fuel filter. A member suggested it for the rev problem.
3. Faulty idle air control valve. A member's similar-era car had this problem.

What it usually costs

No owner posted prices.

Is it safe to keep driving?

A car that won't rev or surges can't keep up with traffic. Verify with a mechanic before relying on it.

DIY or shop?

DIY-friendly for filters and idle valve checks. Draining a tank and pump work are easier at a shop.

Recalls, bulletins and complaints in plain words

• Recalls: NHTSA lists no recall for starting or the fuel system on the Nissan Stanza in the model years we could check on 2026-10-26 (the recall lookup returned an error for 4 model-year queries). Check your VIN at nhtsa.gov/recalls. If your car is part of a recall, the dealer fixes it for free.
• NHTSA complaints: 38 keyword-matched complaints for Nissan Stanza 1982–1992 (of 167 unique complaints queried, NHTSA complaints API by model year, queried 2026-10-26; keywords: won't start, no start, stall, fuel pump, idle, hesitation, surge). This counts complaints that mention these words. It is not a defect finding.

What owners report

• In 1987 Nissan Stanza won't start after sitting 5 years on Car Talk, an owner put new fuel in a Stanza that had sat five years; it cranked but wouldn't start, and starting fluid only got it running briefly. A member asked whether the tank had been drained, since old fuel may already have ruined the pump, and whether it had spark and good compression.
• In Help intermittent acceleration problem on Car Talk, a 1990 Stanza five-speed owner said it usually ran fine, but sometimes the revs climbed and dropped repeatedly and wouldn't build. Members asked about a check engine light and fuel filter, noted this OBD I car's codes are hard for shops to read, and one said a similar-era car had a faulty idle air control valve.

Quick tip

Old gas is the enemy of a stored car. Draining the tank first costs less than the pump you'll ruin by cranking on varnish.

Safety / mechanic note

Starting fluid is flammable; use it sparingly and never near a flame. Verify with a mechanic.
